Seminar by Prof. Giorgio Ferrari in Padova and via Zoom!
by Giorgia Callegaro 03 Jul '21

03 Jul '21

Dear all, it's a pleasure to announce the forthcoming seminar by Giorgio Ferrari, which will be held in room 2BC30 of the Mathematics Department (Torre Archimede) of the University of Padova and online, via Zoom, next week. Here are the details: * Date and time: 7 July, 14.30 pm * Title: Multidimensional singular control and related Skorokhod problem: sufficient conditions for the characterization of optimal controls * Abstract: Singular stochastic control problems naturally arise in applications and are intimately related to variational inequalities and free-boundary problems. A key difficulty in the analysis of singular stochastic control problems in multiple dimensions concerns the characterization of an optimal policy, being the latter typically related to the construction of a stochastic process with reflecting boundary conditions. In this talk we show how to construct the optimal control for a class of singular stochastic control problems as the unique solution to a related Skorokhod reflection problem. The considered optimization problems concern the minimization of a discounted cost functional over an infinite time-horizon through a process of bounded variation affecting an Itô-diffusion. The setting is multidimensional, the dynamics of the state and the costs are convex, the volatility matrix can be constant or linear in the state. We prove that the optimal control acts only when the underlying diffusion attempts to exit the so-called waiting region, and that the direction of this action is prescribed by the derivative of the value function. Our approach is based on the study of a suitable monotonicity property of the derivative of the value function through its interpretation as the value of an optimal stopping game. Such a monotonicity allows to construct nearly optimal policies which reflect the underlying diffusion at the boundary of approximating waiting regions. The limit of this approximation scheme then provides the desired characterization. Our result applies to a relevant class of linear-quadratic models, among others. Furthermore, it allows to construct the optimal control in degenerate and non degenerate settings considered in the literature, where this important aspect was only partially addressed. The talk is based on a joint work with Jodi Dianetti. * Zoom link: please visit the webpage https://www.math.unipd.it/news/multidimensional-singular-control-and-relate… Thanks for your attention and see you soon in Padova, Giorgia Callegaro -- Giorgia Callegaro Associate Professor Department of Mathematics - University of Padova Via Trieste 63 , I-35121 Padova - ITALY Tel: +39-0498271481 Fax: +39-0498271499 E-Mail: gcallega(a)math.unipd.it <https://webmail.math.unipd.it/horde3/imp/message.php?mailbox=Sent&index=598#> Personal web-page: https://sites.google.com/site/giogiocallegaro/Home

Online seminar by Matteo Brachetta (Polimi), July 14, 17:00
by Elisa Mastrogiacomo 01 Jul '21

01 Jul '21

*** Apologize for cross-posting *** On *July 14 at 17:00, Matteo Brachetta* (Department of Mathematics, Politecnico di Milano <https://scholar.google.com/citations?view_op=view_org&hl=it&org=39070900387…>) will give a virtual seminar “in Insubria & Bicocca”, to which you are all invited. You can find the title and abstract below. Title: *Optimal Public Debt Management* Abstract: Public debt management is one of the most relevant topics in Economics, especially after economic crises due to wars, pandemics or economic recession. We discuss a class of debt management problems in a stochastic environment model. We propose a model for the Debt-to-GDP ratio where the government interventions (via fiscal policies) affect the public debt and the GDP growth rate at the same time. We allow for a stochastic interest rate on debt and possible correlation with the GDP growth rate. Indeed, both the interest rate and the GDP growth depend on a stochastic factor, which may represent any relevant macroeconomic variable, such as economic conditions. Moreover, shocks on debt and GDP can be correlated. We tackle the problem of a government whose goal is to determine the fiscal policy (quantity of surplus or deficit) in order to minimize a general functional cost. We prove that the value function is a viscosity solution to the Hamilton-Jacobi-Bellman equation and provide a Verification Theorem based on classical solutions. Then we discuss two applications, namely debt reduction and debt smoothing, providing explicit results. The seminar will be on *Zoom*. You can find the information to join below.

pst-doc in Statistics, University of Florence
by Monia Lupparelli 29 Jun '21

29 Jun '21

* Apologise for cross-posting * Dear Colleagues, I would like to inform you that a post-doc in Statistics is available in the Department of Statistics, Computer Science, Applications at the University of Florence, under the supervision of Prof. Monia Lupparelli and Prof. Francesco C. Stingo. Deadline for application: July 12th 2021 Starting date: November 1st 2021 Research topic: Bayesian model search for profile undirected graphical models The research project aims to develop a graphical modelling approach to study the effect that a risk factor may have on a set of random variables and on their joint dependence structure. This issue could be partially addressed by using chain graph or multiple graph models: the first method ignores how the dependence structure may vary under different profiles defined by the external factor, the second does not account for the effect of the factor on single variables. The research should develop a class of profile graphical models to fill the gap between the existent graphical approaches. As far as inference is concerned, model selection represents a crucial aspect since compatibility constraints for the model identifiability need to be considered. The idea is to implement Bayesian stochastic search approaches for the selection and inference of discrete profile graphs, both for moderate and high dimensional data. The proposed methodology will be applied to biomedical data.

by Massimiliano Gubinelli 25 Jun '21

25 Jun '21

Cari colleghi, insieme ad altri ricercatori da molti anni sviluppiamo un editor di testi scientifici (e non) che si chiama TeXmacs (www.texmacs.org) e che permette di scrivere articoli, preparare presentazioni, etc.. rimpiazzando l'uso dei vari sistemi basati su TeX con un'interfaccia più sintetica e moderna. TeXmacs non è basato su TeX ma può esportare i documenti in vari formati, tra cui HTML, PDF o appunto (La)TeX. Il software è libero, parte del progetto GNU (per chi conosce questa iniziativa e i suoi scopi) e compatibile con Mac, Windows e i vari sistemi Linux. È un sistema che per molti di noi è diventato uno strumento di uso quotidiano, sia nella didattica (sopratutto in questo periodo di insegnamento a distanza) che nella ricerca e nella produzione di documentazione scientifica: articoli, tesi, libri. Da poco abbiamo rilasciato la versione 2.1 che rappresenta il consolidamento del nostro lavoro dell'ultimo decennio e all'occasione cerchiamo di fare un po' di pubblicità all'iniziativa per favorirne la diffusione. In particolare abbiamo prodotto un corto video di presentazione (~4 min) che riassume le caratteristiche salienti del sistema: https://www.youtube.com/watch?v=H46ON2FB30U In rete trovate anche varie risorse di informazione: un sito web dove scaricare il programma, un forum e delle liste di diffusione. Per maggiori dettagli faccio seguire il messaggio ufficiale in inglese. Sperando che questa iniziativa possa essere di interesse e utile, vi porgo cordiali saluti, Massimiliano Gubinelli -------------------------------------------------------------------- Dear colleague, We are happy to announce the release of GNU TeXmacs 2.1, a free scientific office suite that you may download from https://www.texmacs.org The core of the system is a what-you-see-is-what-you-get structured text editor with support for mathematical formulas. For a short overview, you may watch the following video (3 min 40): https://www.youtube.com/watch?v=H46ON2FB30U TeXmacs is unique in its ability to produce documents with the highest typographical quality using a user friendly interface. The software also comes with an integrated presentation tool, a picture editor, version control, a bibliography tool, interfaces to various mathematical computation systems, and much more... GNU TeXmacs is not based on TeX/LaTeX, but comes with high quality converters from and to LaTeX, as well as Html/MathML/MathJax. In order to get started with TeXmacs, we recommend that you watch one or more of our introductory videos: https://www.texmacs.org/tmweb/home/videos.en.html The software provides integrated documentation and a manual that can be downloaded from https://www.texmacs.org/tmweb/help/book.en.html A new book about TeXmacs is available here: https://www.scypress.com/book_info.html For further questions, don't hesitate to ask on one of our mailing lists or on the TeXmacs forum.

Please find below the abstract and the zoom links. Best regards, Luca Regis <#> <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/SNnQ5aISnSkDsUrrKkdJ5noQSxbj4pJWMq…> <#> LTI@Unito and Fondazione Collegio Carlo Alberto are pleased to invite you to the following webinars <#> *June 29, 2021 | 12:00 - 13:00* *“On The Impact of Long Term Investors on Information Choice and Market Efficiency”* *Matthijs Breugem (Collegio Carlo Alberto)* <#> *Abstract* We analyze the impact of investor investment horizon on information acquisition and market efficiency in an REE economy with short-term and long-term investors. We find that the presence of long-term investors increases the willingness of short-term investors to acquire long-term information. Specifically, short-term investors care about long-term information to the extent that future prices—at which they liquidate their investments—reflect long-term payoffs. Long-term investors acquire long-term information and therefore increase the price-informativeness of future prices. Therefore, the larger the fraction of long-term investors, the more long-term payoffs are reflected into future prices, and the more long-term information is acquired by short-term investors. *Zoom Link:* *https://us02web.zoom.us/j/83290754621?pwd=Q3NoaWlIdXpnSkovdjlRTXE1OE5jdz09 <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/PA1lvCniowZZn-8vKUfINTd51_6qus8e1k…>* Meeting ID: 832 9075 4621 Passcode: 359187 <#> *July 1, 2021 | 12:00 - 13:00* *“Option-Implied Dependence and Correlation Risk Premium”* *Carole Bernard (Grenoble Ecole de Management)* <#> *Abstract* We propose a novel model-free approach to obtain the joint risk-neutral distribution among several assets that is consistent with market prices of options on these assets and their weighted index. In an empirical application, we use options on the S&P 500 index and its nine industry sectors. The results of our analysis reveal that the option-implied dependence for the nine sectors is highly nonnormal, asymmetric, and time-varying. We then study two conditional correlations: when the market moves down or up. The risk premium for the down correlation is strongly negative, while the opposite is true for the up correlation. These findings are consistent with the economic intuition that investors dislike the loss of diversification when markets fall, but they actually prefer high correlation when markets rally. *Zoom link: * *https://us02web.zoom.us/j/81288915014?pwd=YjEzZVpIcG9XV0dIQ0VIT3U1MlNvQT09* <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/UPvaJBcnB9yu8Re-TR7dBnNYNJyWPZXbUf…> Meeting ID: 812 8891 5014 Passcode: 967992 <#> <#> <#> <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/iyOIzzg_nVx7Bu3-NolrUvwYpV1JmU_hFp…> <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/Et9Pc4YQXTY89y_CV5p_IUhO4DxipOFuoI…> <#> FONDAZIONE COLLEGIO CARLO ALBERTO Piazza Arbarello 8 - 10122 Torino, Italy phone: +390116705000 segreteria(a)carloalberto.org - www.carloalberto.org Facebook <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/yVeI_QEUL9xx9EqhVQgfTjU0cwCU5_VhvC…> Twitter <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/0kMzTVLZsJ-Syk4mMhudyxU14AXIlPy9yW…> LinkedIn <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/QYDynuy101bf3yF94teX10r5klyqsB8YBx…> Instagram <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/qnxIbHpfFwuutvK3uttAeswc2cRYOxE0tz…> Youtube <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/_BlSIp8G775XAxS37E-KhH0lDg1opLCsE-…> <#> *INFORMATION UNDER THE NEW GENERAL DATA PROTECTION REGULATION (GDPR)* Your personal information has been gathered for the exclusive purpose of informing you about the Collegio's initiatives, considering our and your legitimate interest or your consent.

(PMS)^2 online talk: Lucia Caramellino [Monday June 28 at 5:30pm]
by Maurizia Rossi 23 Jun '21

23 Jun '21

Dear colleagues, we are happy to announce the following online talk: Speaker: *Lucia Caramellino* (Università di Roma "Tor Vergata") Title: *Regularization lemmas and convergence in total variation.* Abstract: We provide a simple abstract formalism of integration by parts under which we obtain some regularization lemmas. These lemmas apply to any sequence of random variables which are smooth and non-degenerated in some sense and enable one to upgrade the distance of convergence from a smooth (Wasserstein e.g.) distance to the total variation in a quantitative way. We provide a result removing the costly assumption that some non-degeneracy is required along the whole sequence, as we require only non-degeneracy at the limit. The price to pay is to control the smooth distance between the Malliavin matrix of the sequence and the Malliavin matrix of the limit which is particularly easy in the context of Gaussian limits as their Malliavin matrix is deterministic. We show some applications of this result. >From joint papers with Vlad Bally and Guillaume Poly. Date and time: * Monday June 28, 17:30-18:30 (Rome time zone)* *Zoom link: * https://us02web.zoom.us/j/82036797456?pwd=bFpXZndKOHFxOTNrUkd0OVhub09qZz09 ID riunione: 820 3679 7456 Passcode: t0Db9B This is a talk of the *(PMS)^2: Pavia-Milano Seminar series on Probability and Mathematical Statistics *organized jointly by the universities Milano-Bicocca, Pavia, Milano-Politecnico and Milano-Statale.

Buongiorno vi giro l'annuncio del OWPS di domani (notate che nella mail scrivono June 25 ma poi hanno mandato una seconda mail di rettifica). Buona giornata Alessandra ---------- Forwarded message --------- Da: One World Probability <ow.probability(a)gmail.com> Date: mer 23 giu 2021 alle ore 08:14 Subject: [owps] OWPS Talks June 25 To: <owps(a)lists.bath.ac.uk> Dear All, Thursday June 25 we have a session on Probability Theory and Population Genetics, Speakers: Cornelia Pokalyuk and Anton Wakolbinger. This is the last session before the summer break! (Note: the time is in UTC. Due to time changes, you should check what that translates to in your location) ------------------------------------------------ (14:00-16:00 UTC) Speakers: Cornelia Pokalyuk and Anton Wakolbinger Fixation of slightly beneficial alleles from a backward and a forward perspective Cornelia Pokalyuk and Anton Wakolbinger (Goethe Universität Frankfurt) For a slightly beneficial mutant whose mean offspring number is by a factor 1+s larger than that of the wild types, the probability of being established in a large population is \approx 2s/v^2, where v^2 is the offspring variance. This approximation has been derived (for v^2=1) by Haldane (1927). In our tandem talk we will present some mathematics behind and beyond Haldane's formula within the class of Cannings models (which in the neutral case generalize the prototypic Wright-Fisher model from multinomial to exchangeable offspring numbers). It turns out that for ``moderately strong'' selection the {\em forward perspective} of the Galton-Watson approximation helps to prove the Haldane asymptotics in the large population limit, whereas for ``moderately weak'' selection a {\em backward perspective} is appropriate, which relies on an ancestral selection graph in discrete time. These parts of the presentation are based on F. Boenkost, A. Gonz\’alez Casanova, C.P., A.W., Haldane's formula in Cannings models: - The case of moderately weak selection, Electron. J. Probab. 26(4) (2021) - The case of moderately strong selection, arXiv:2008.02225 [1] [math.PR], submitted. In the last part of the talk we will give an outlook on work in progress on analoga of Haldane's formula for a class of Cannings models with asymptotically infinite offspring variance. A.

(Note: all times are in UTC. Due to time changes, you should check what that translates to in your location) ------------------------------------------------ (14:00-15:00 UTC) Speaker: Amir Dembo Sparse random graphs with unusually large subgraph counts In this talk, based on joint works with Nicholas Cook, Huy Tuan Pham and Sohom Bhattacharya, I will discuss recent developments in the emerging theory of nonlinear large deviations, focusing on sharp upper tails for counts of several fixed subgraphs in a large sparse random graph (such as Erdős–Rényi or uniformly d-regular). These results allow in turn to determine the typical structure of samples from an associated class of Gibbs measures, known as Exponential Random Graph Models, which are widely used in the analysis of social networks. (14:00-15:00 UTC) Speaker: Nicholas Cook Large deviations and the regularity method for the Erdős–Rényi (hyper)graph I will describe a quantitative approach to the large deviations of random graphs and hypergraphs, emphasizing connections with graph limit theory and the regularity method from extremal combinatorics. The approach rests on new decomposition theorems and counting lemmas for sparse hypergraphs, formulated in terms of a novel class of cut-type norms for Bernoulli tensors. Based on joint work with Amir Dembo and Huy Tuan Pham. The Zoom link is on the OWPS webpage.

Padova Online Seminar by Paolo Dai Pra (Università di Verona) [Friday, June 25 at 14.30]
by alessandra bianchi 14 Jun '21

14 Jun '21

Dear Colleagues, We would like to invite you to the following Probability seminar that will take place on June 25 at 14.30 by the zoom platform. ________________________________________________________ Speaker: Paolo Dai Pra (Università di Verona) Title: The social dilemma of stubborness vs. herding in social decisions: a mean field (game) model. 25 JUNE (Friday) - 14:30 zoom link: TBA available on the webpage https://www.math.unipd.it/~bianchi/seminari/ ) Abstract: We study a mean field game in continuous time over a finite horizon, T, where the state of each agent is binary and where players base their strategic decisions on two, possibly competing, factors: the willingness to align with the majority (herding) and the aspiration of sticking with the own type (stubbornness). While the corresponding N-player game possesses a unique Nash equilibrium, the mean field game has a variety of equilibria and phase transitions. The large N limit of the unique equilibrium of the N-player game selects one equilibrium of the mean field game; this selection appears to be highly nontrivial and will be discussed mostly on the base of simulations. -- Alessandra Bianchi Dip. di Matematica Università di Padova Via Trieste, 63 - 35121 Padova, Italy phone: +39 049 827 14 06 fax: +39 049 827 14 28 e-mail: bianchi(a)math.unipd.it http://www.math.unipd.it/~bianchi/

Seminar announcement Thursday 24 - Limit theorems for exponential random graphs (dr. Elena Magnanini)
by Gianmarco Bet 14 Jun '21

14 Jun '21

Dear colleagues, On June Thursday 24 at 15:30, dr. Elena Magnanini (Università degli Studi di Padova) will give a virtual seminar “in Florence”, to which you are all invited. You can find title and abstract below. Title: Limit theorems for exponential random graphs Abstract: In the present talk we focus on the derivation of some asymptotic properties for the family of exponential random graphs. This model can be seen as the generalization of the dense Erdӧs-Rényi random graph and follows the statistical mechanics approach of defining a Hamiltonian to weight the probability measure on the space of graphs, assigning higher mass to graphs with “desirable” properties. In particular our analysis will be focused on the edge-triangle model, a two-parameter family of exponential random graphs where the Hamiltonian only includes edge and triangle densities. We borrow tools from statistical mechanics together with large deviations techniques to obtain limit theorems for the edge density in the so-called replica symmetric regime, where the limiting free energy of the model is known together with a complete characterization of the phase diagram. First, we determine the asymptotic distribution of the edge density, as the graph size n tends to infinity, in the entire replica symmetric regime. We then study the fluctuations of the edge density around its average for all parameter values outside the critical curve and off the critical point and we formulate conjectures about the behavior at criticality based on the analysis of a mean-field approximation of the model. Some of our results can be extended with no substantial changes to more general classes of exponential random graphs. Joint work with Alessandra Bianchi and Francesca Collet. The seminar will be on Zoom. You can find the information to join below.

Below you find the Zoom link and an abstract of the presentation. Best regards, Luca Regis <#> <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/CkeqzI9VH3wAjL0mIewldcmVdn9Kyki4A1…> <#> LTI@Unito and Fondazione Collegio Carlo Alberto are pleased to invite you to the following webinar <#> *June 14, 2021 | 12:45 - 13:45* *“Investor Behavior under Prospect Theory: Evidence from Mutual Funds”* *Lorenzo Schoenleber (Collegio Carlo Alberto)* <#> *Abstract. *This paper studies the investment behavior of investors and fund managers within the mutual funds industry. We find that investors are biased in their mutual fund purchase decisions in a way described by prospect theory: The prospect theory value predicts future mutual fund flows, despite the fact that it is not related to the mutual funds’ future performance. We show that the mutual funds’ prospect theory value contains incremental information compared to historical performance measures already discovered in the mutual fund flow literature, and subsumes the information content of variables related to the convexity in the flow-performance relationship. We find that mutual fund managers are not subject to any behavioral bias identifiable by prospect theory when selecting stocks for their mutual fund portfolio. The results are robust to various specifications. *Zoom Link:* *https://us02web.zoom.us/j/85611292343?pwd=U1dwYXZrZFQvR0RaZGwvZmplS2tFUT09 <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/79Qh76oDew-iI1lTKKd-JiGNLs42TkHRfm…>* Meeting ID: 856 1129 2343 Passcode: 401236 <#> <#> <#> <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/YmtAmHu7JhL3tEkSBLOh9PvpHnMR_PZzOe…> <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/AWpDX3iRxSwhx4MX6D5K64D_f2W6jUS_f2…> <#> FONDAZIONE COLLEGIO CARLO ALBERTO Piazza Arbarello 8 - 10122 Torino, Italy phone: +390116705000 segreteria(a)carloalberto.org - www.carloalberto.org Facebook <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/4RHP7RFelHmPbN3l7D0GqNF1iSMpQHHnP4…> Twitter <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/EPbbUwncGLMOBC2qw2aNITsMvBTfaFVZcL…> LinkedIn <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/DcHnPK_RQAOSwsn5P0Ykl5hEaDyjahuL3n…> Instagram <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/EUM8gEcq3q4LvNepOA15xKXC8xWWbOaKbx…> Youtube <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/9VeN44_sxivBMcSIflgJy1DuZHDI0j6YLh…> <#> *INFORMATION UNDER THE NEW GENERAL DATA PROTECTION REGULATION (GDPR)* Your personal information has been gathered for the exclusive purpose of informing you about the Collegio's initiatives, considering our and your legitimate interest or your consent.

Dear colleagues, we are happy to announce the following online talk: Speaker: Vincent Martinez (CUNY Hunter College) Title: On unique ergodicity, regularity, and mixing for the weakly-damped stochastic KdV equation. Abstract: We discuss the existence, uniqueness, and regularity of invariant measures for the damped-driven stochastic Korteweg-de Vries equation, where the noise is additive and sufficiently non-degenerate. It is shown that a simple, but versatile control strategy, typically employed to establish exponential mixing for strongly dissipative systems such as the 2D Navier-Stokes equations, can nevertheless be applied in this weakly dissipative setting to establish elementary proofs of both unique ergodicity, albeit without mixing rates, as well as regularity of the support of the invariant measure. Under the assumption of large damping, however, a one-force, one-solution principle is established, from which we are able to deduce the existence of a spectral gap with respect to a Wasserstein distance-like function. Date and time: Monday June 14, 17:30-18:30 (Rome time zone) Zoom link: https://us02web.zoom.us/j/85740643260?pwd=SzFjTXo0bWE3YjI3VWo0b3krT09kdz09 ID riunione: 857 4064 3260 Passcode: w7yJLi This talk is the fourth of the (PMS)^2: Pavia-Milano Seminar series on Probability and Mathematical Statistics organized jointly by the universities Milano-Bicocca, Pavia, Milano-Politecnico and Milano-Statale.

Conference at CIRM
by Giovanni Conforti 08 Jun '21

08 Jun '21

Cari colleghi, Ecco l'annuncio di una conferenza al CIRM di Marsiglia che potrebbe interessarvi. Giovanni Dear All, We are happy to announce the upcoming conference “Schrödinger Problem and Mean-field PDE Systems: Computational and Theoretical Advances” taking place at CIRM in Luminy, France from Nov. 15 to Nov. 19 2021. The webpage of the event is publicly available at https://conferences.cirm-math.fr/2413.html and you can find below a brief description of the themes of the conference. Registration is open until July 1st. At the moment we aim for a hybrid (online+in person) conference, but this could change depending on the development of the pandemic. Limited funding is available for junior participants or participants who cannot support themselves. Moreover, there are also some free slots for contributed talks. We hope to see you soon, in whichever form. Best regards, the organizers. Julio Backhoff, Guillaume Carlier, Giovanni Conforti, Ivan Gentil, Daniela Tonon. -------------------------------------------------------------------------------------------------------------------------------------------- “Schrödinger Problem and Mean-field PDE Systems: Computational and Theoretical Advances” Monge’s question of how to optimally move sand-pile stands at the origin of the modern theory of optimal transport. The development of this theory over the last decades led to impressive advances in analysis and geometry, reaching out to applied fields such as economics and machine learning. One and a half century after Monge, Schrödinger asked: “What is the most likely evolution of a cloud of random particles conditionally on the observation of their initial and final configurations? "This question, going under the name of Schödinger Problem, initiated a research line that has grown enormously in the last years since it was understood that Schrödinger’s and Monge’s questions are the same when the fluctuations of the random particles are very small. This discovery offered a natural ground for the theories of optimal transport and large deviations to meet and thrive together. At the same time, it also inspired the use of entropic regularization techniques in machine learning and numerics for PDEs, achieving major computational advantages. Asking Schrödinger’s question for strategic particles is the gateway to connect the Schrödinger problem and large deviations with the theory of mean field stochastic control and planning mean field games. This brings to light new mathematical questions. Can entropic regularization speed up the computation of Nash equilibria? Are there new functional inequalities that capture the ergodic behaviour of mean field games? Bringing together researchers from the areas of probability, optimal transport, statistical machine learning and mean field games, this conference aims to strengthen the interplay between the Schrödinger problem and mean field systems, and facilitate the birth of novel methodologies and results.

02 Jun '21

Buongiorno, inoltro l'annuncio del OWPS per chi fosse interessato. Grazie per l'attenzione. Saluti Alessandra ---------- Messaggio inoltrato ---------- Da: *One World Probability* <ow.probability(a)gmail.com> Data: mercoledì 2 giugno 2021 Oggetto: [owps] OWPS: two talks thursday June 3 A: owps(a)lists.bath.ac.uk Dear All, we have two talks tomorrow, by Gerard Ben Arous and Benjamin McKenna, see below. Remember that we start 14:00 UTC which is 16:00 CET! 14:00-15:00 Gerard Ben Arous The topology of the elastic manifold This is joint work with Paul Bourgade and Benjamin McKenna (both Courant Institute, NYU) and relies on the joint recent papers arXiv:2105.05051 and arXiv:2105.05000. The elastic manifold is a paradigmatic representative of the class of disordered elastic systems. These models describe random surfaces with rugged shapes resulting from a competition between random spatial impurities (preferring disordered configurations), on the one hand, and elastic self-interactions (preferring ordered configurations), on the other. The elastic manifold model is interesting because it displays a depinning phase transition and has a long history as a testing ground for new approaches in statistical physics of disordered media, for example for fixed dimension by Fisher (1986) using functional renormalization group methods, and in the high-dimensional limit by Mézard and Parisi (1992) using the replica method or by Le Doussal-Mueller-Wiese (2007) which relies on functional renormalization group. We study the topology of the energy landscape of this model in the Mézard-Parisi setting, and compute the (annealed) topological complexity both of total critical points and of local minima. Our main result confirms the recent formulas obtained by Fyodorov and Le Doussal (2020). It identifies the boundary between simple and glassy phases, as well as the nature of the phase transition. The main argument relies naturally on Random Matrix Theory, through the Kac-Rice formula. 15:00 - 16:00 UTC Benjamin McKenna Random determinants beyond invariance This is partially joint work with Gérard Ben Arous and Paul Bourgade (both Courant Institute, NYU) and relies on the recent joint paper arXiv:2105.05000 and solo paper arXiv:2105.05043. To study the topology of high-dimensional random functions via the Kac-Rice formula, the core requirement is the analysis of the asymptotic behavior of large random determinants in the exponential scale. For models like the elastic manifold, these random determinants are not invariant under the usual groups of symmetries, as for usual models of spherical spin glasses for instance. Thus their asymptotic evaluation is rather delicate. We give an abstract result for the behavior of large random determinants beyond the invariant case, which cover many other interesting models beyond the elastic manifold. As an example of one such model, we discuss bipartite spherical spin glasses. The Zoom link is on the OWPS webpage.

Pisa Online Seminars - J. Corujo and W. Van Zuijlen (Tuesday, June 8 at 15:00 and 16:00)
by Giacomo Filippo Di Gesu 02 Jun '21

02 Jun '21

Dear colleagues, I would like to invite you to the following online seminar organized by the Probability group of the University of Pisa. The two talks will be accessible under the link Click here to join<https://teams.microsoft.com/l/meetup-join/19:af3d635091e049579e555a84219ab3…"Tid":"c7456b31-a220-47f5-be52-473828670aa1","Oid":"dfd1e5f6-331d-43e0-a180-4bb6ce727fb7"}> Best regards, Giacomo Tuesday, June 8, 15:00 Speaker: Josué Corujo (Université Paris Dauphine) Title: Spectrum and ergodicity of a neutral multi-allelic Moran model Abstract: We will present some recent results on the study of a neutral multi-allelic Moran model, which is a finite continuous-time Markov process. For this process, it is assumed that the individuals interact according to two processes: a mutation process where they mutate independently of each other according to an irreducible rate matrix, and a Moran type reproduction process, where two individuals are uniformly chosen, one dies and the other is duplicated. During this talk we will discuss some recent results for the spectrum of the generator of the neutral multi-allelic Moran process, providing explicit expressions for its eigenvalues in terms of the eigenvalues of the rate matrix that drives the mutation process. Our approach does not require that the mutation process be reversible, or even diagonalizable. Additionally, we will discuss some applications of these results to the study of the speed of convergence to stationarity of the Moran process for a process with general mutation scheme. We specially focus on the case where the mutation scheme satisfies the so called "parent independent" condition, where (and only where) the neutral Moran model becomes reversible. In this later case we can go further and prove the existence of a cutoff phenomenon for the convergence to stationarity. This presentation is based on a recently submitted work, for which a preprint is available at https://arxiv.org/abs/2010.08809. Tuesday, June 8, 16:00 Speaker: Willem Van Zuijlen (WIAS) Title: Total mass asymptotics of the parabolic Anderson model Abstract: We consider the parabolic Anderson model with a white noise potential in two dimensions. This model is also called the stochastic heat equation with a multiplicative noise. We study the large time asymptotics of the total mass of the solution. Due to the irregularity of the white noise, in two dimensions the equation is a priori not well-posed. Using paracontrolled calculus or regularity structures one can make sense of the equation by a renormalisation, which can be thought of as ''subtracting infinity of the potential''. To obtain the asymptotics of the total mass we use the spectral decomposition, an alternative Feynman-Kac type representation and heat-kernel estimates which come from joint works with Khalil Chouk, Wolfgang König and Nicolas Perkowski. ************************ Giacomo Di Gesù Dipartimento di Matematica Università di Pisa Largo Bruno Pontecorvo 5 56127 - Pisa, Italy giacomo.digesu(a)unipi.it<mailto:giacomo.digesu@unipi.it> https://sites.google.com/site/giacomodigesu/

Seminar on Stochastic Games by M. MNIF "in Padova" (Zoom)
by Giorgia Callegaro 02 Jun '21

02 Jun '21

Dear colleagues, this email is to announce the Probability and Finance seminar of this week, "in Padova" (Zoom). Here are the details: * Speaker: *M. MNIF* (University of Monastir, Tunisia) * Title: *Nonzero-sum stochastic Impulse Games with an application in competitive retail energy markets* * Date: *Friday June 4*, 2021 at 3 pm (ITA time) * Abstract: We study a nonzero-sum stochastic differential game with both players adopting impulse controls, on a finite time horizon. We derive the corresponding system of quasi-variational inequalities (QVIs in short). We prove, by means of the weak dynamic programming principle for the stochastic differential game, that the value function of each player is the unique viscosity solution to the associated QVIs system. We present a probabilistic numerical scheme which approximates the solution of the QVIs system and we give some numerical results. *** Zoom link: https://unipd.zoom.us/j/85706083496 Have a nice day, Giorgia Callegaro -- Giorgia Callegaro Associate Professor Department of Mathematics - University of Padova Via Trieste 63 , I-35121 Padova - ITALY Tel: +39-0498271481 Fax: +39-0498271499 E-Mail: gcallega(a)math.unipd.it <https://webmail.math.unipd.it/horde3/imp/message.php?mailbox=Sent&index=598#> Personal web-page: https://sites.google.com/site/giogiocallegaro/Home

Webinar Volgushev @Bocconi
by Giacomo Zanella 31 May '21

31 May '21

We announce the following webinar from the Statistics Series at Università Bocconi: Date: Thursday, June 3rd, h17:00 (Italy time) Speaker: Stanislav Volgushev (University of Toronto) Title: Structure learning for Extremes Abstract: Extremal graphical models are sparse statistical models for multivariate extreme events. The underlying graph encodes conditional independencies and enables a visual interpretation of the complex extremal dependence structure. For the important case of tree models, we provide a data-driven methodology for learning the graphical structure. We show that sample versions of the extremal correlation and a new summary statistic, which we call the extremal variogram, can be used as weights for a minimum spanning tree to consistently recover the true underlying tree. Remarkably, this implies that extremal tree models can be learned in a completely non-parametric fashion by using simple summary statistics and without the need to assume discrete distributions, existence of densities, or parametric models for marginal or bivariate distributions. Extensions to more general graphs are also discussed.

Seminari Prisma 7 Giugno
by Domenico Marinucci 29 May '21

29 May '21

Cari colleghi il prossimo incontro per il ciclo di seminari Prisma (speaker: Francesco Caravenna e Maurizia Rossi) si svolgerà lunedì 7 Giugno alle ore 16 sulla piattaforma Teams; qui sotto il link, i titoli e gli abstract. Grazie per l'attenzione, Domenico Marinucci e Claudia Ceci Link collegamento: https://teams.microsoft.com/l/meetup-join/19%3a667d2414be564c5d8fba30acffeb… Speaker: Francesco Caravenna (Università di Milano-Bicocca) Title: Central limit theorems in disordered systems and stochastic PDEs Abstract: I will present some recent convergence results toward Gaussian processes, that arise from statistical mechanics models and stochastic PDEs connected to the so-called KPZ equation. These results may be viewed as generalised central limit theorems and they can be proved with a blend of old and new techniques, whose wide interest I will try to illustrate. %%%%%%%%%%%%%%%%%%%%%%%%%% Speaker: Maurizia Rossi (Università di Milano-Bicocca) Title: The geometry of random waves Abstract: In this talk we investigate the behavior of the "typical" eigenfunction of a compact Riemannian manifold. In particular, motivated by both Yau's conjecture on nodal sets and Berry's ansatz on planar random waves, we consider random spherical harmonics and study the distribution of the length of their nodal lines for large eigenvalues. These results raise several questions regarding both the distribution of other geometric functionals of excursion sets at any level and the behavior of nodal statistics of random eigenfunctions of a "generic" manifold. In this talk we answer some of these questions, relying on recent developments in the theory of local geometry of random fields and Gaussian Kinematic Formulae à la Adler & Taylor. %%%%%%%%%%%%%%%%%%%%%%%%%% -- @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ Domenico Marinucci Dipartimento di Matematica Università di Roma Tor Vergata https://www.mat.uniroma2.it/~marinucc/ @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@

LTI@Unito webinar Andrea Modea (U. Bonn): “Recapitalization, Bailout, and Long-run Welfare in a Dynamic Model of Banking”| May 24, 2021 @12:45

20 May '21

Dear Colleagues, I am happy to share with you the following invitation to the Quantative Finance webinar organized by LTI@UniTO and Collegio Carlo Alberto, “Recapitalization, Bailout, and Long-run Welfare in a Dynamic Model of Banking” by Andrea Modena (University of Bonn), which will take place on Zoom on May 24, at 12.45. Below you find the Zoom link and an abstract of the presentation. Best regards, Luca Regis <#> <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/J7QJ4oN6YVj_zZsZOtARrIVf6c7Hmq99bS…> <#> LTI@Unito and Fondazione Collegio Carlo Alberto are pleased to invite you to the following workshop <#> *May 24, 2021 | 12:45 - 13:45* *“Recapitalization, Bailout, and Long-run Welfare in a Dynamic Model of Banking”* *Andrea Modena (University of Bonn, Università Ca’ Foscari Venezia) * <#> *Abstract. *We study the trade-off between the short-run costs and the long-run benefits of bank bailouts. In the model, banks leverage, thanks to their cost advantage at monitoring firms, but hold precautionary capital buffers to avoid costly equity issuance. Banks’ recapitalization is suboptimal because they do not internalize the externalities of the banking sector’s relative size on their individual leverage capacity and firms’ investments. Systematic bailouts can improve the allocation efficiency in bad states, in which banks’ leverage is persistently constrained and investments are low. In the long run, bailouts accelerate the economy’s recovery by fostering growth, thereby reducing endogenous risk. *Zoom link:* *https://us02web.zoom.us/j/83596624662?pwd=ZmlvenJSbGJVZjl4WTA0MnNMUXVlZz09* <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/s-qJVnhbS_zG1dfsi6qOu9mnfTxc8QKO7h…> Meeting ID: 835 9662 4662 Passcode: 056057 <#> <#> <#> <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/yuwpD8sTuPk6FHLiRKKpTMm-UjUyfN6wgb…> <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/VpUegKgodGXzBen7C44jhlkXkF9jhsSmmo…> <#> FONDAZIONE COLLEGIO CARLO ALBERTO Piazza Arbarello 8 - 10122 Torino, Italy phone: +390116705000 segreteria(a)carloalberto.org - www.carloalberto.org Facebook <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/cMWe7pVTdvfxQ1F14Ip-99gRFCuIRpXB8y…> Twitter <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/PBGBAvJh5x5DlI_7sK-JDvUzZNEYzjMddC…> LinkedIn <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/ODY9SQh8giPEbUl9tQNsfhNYuPH1kUrrxH…> Instagram <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/eSYLTqj79odIe23NOKQ9iD17xZiiWLxZpk…> Youtube <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/VHxNOf4LAHpDbLIqIRMcZ1IjxJ8vJMlt0R…> <#> *INFORMATION UNDER THE NEW GENERAL DATA PROTECTION REGULATION (GDPR)* Your personal information has been gathered for the exclusive purpose of informing you about the Collegio's initiatives, considering our and your legitimate interest or your consent.

(PMS)^2 online talk: Alessandra Bianchi, Monday May 24 at 17.30
by Carlo Orrieri 19 May '21

19 May '21

Dear colleagues, We are happy to announce the following online talk: Speaker: Alessandra Bianchi (Università di Padova) Title: Limit Theorems for Exponential Random Graphs. Abstract: Exponential Random Graphs are defined through probabilistic ensembles with one or more adjustable parameters. They can be seen as a generalization of the classical Erdos Renyi random graph, obtained by defining a tilted probability measure that is proportional to the densities of certain given finite subgraphs. In this talk we will focus on the edge-triangle model, that is a two-parameter family of exponential random graphs in which dependence between edges is introduced through triangles. Borrowing tools from statistical mechanics, together with large deviations techniques, we will characterize the limiting behavior of the edge density for all parameters in the so-called replica symmetric regime, where a complete characterization of the phase diagram of the model is accessible. First, we determine the asymptotic distribution of this quantity, as the graph size tends to infinity, in the various phases. Then we study the fluctuations of the edge density around its average value off the critical curve and formulate conjectures about the behavior at criticality based on the analysis of a mean-field approximation of the model. Joint work with Francesca Collet and Elena Magnanini. Date and time: Monday May 24, 17:30-18:30 (Rome time zone) Zoom link: https://us02web.zoom.us/j/81602205122?pwd=Wlk0SVZPRjY4UHFzR1c5RmJMekRCZz09 <https://us02web.zoom.us/j/81602205122?pwd=Wlk0SVZPRjY4UHFzR1c5RmJMekRCZz09> Meeting ID: 816 0220 5122 Passcode: d5v0SS This talk is the second of the (PMS)^2: Pavia-Milano Seminar series on Probability and Mathematical Statistics organized jointly by the universities Milano-Bicocca, Pavia, Milano-Politecnico and Milano-Statale. Participation is free and welcome! (though limited to 100 participants for technical reasons) Best regards The organizers (Mario Maurelli, Carlo Orrieri, Maurizia Rossi, Margherita Zanella)

WEBINARS IN STATISTICS @ COLLEGIO CARLO ALBERTO <https://www.carloalberto.org/events/category/seminars/seminars-in-statistic…> Venerdi 21 Maggio 2021, alle ore 12.00, si terrà il seguente webinar: ------------------------------------------------ Speaker: *Paul Jenkins *(University of Warwick) Title: *Asymptotic genealogies of interacting particle systems* Join Zoom Meeting https://us02web.zoom.us/j/87319216872?pwd=L1JnR0UvamZ2RC9Eb2xFbW9qREN0Zz09 Meeting ID: 873 1921 6872 Passcode: 626226 Abstract: Interacting particle systems are a broad class of stochastic models for phenomena arising in physics, engineering, biology, and finance. A prominent class of such models can be expressed as a sequential Monte Carlo algorithm in which the aim is to construct an empirical approximation to a sequence of measures. The approximation is constructed by evolving a discrete-time, weighted population of particles, alternating between a Markov update and a resampling step. Resampling gives rise to a notion of a genealogy in which duplicated particles are regarded as offspring of their parents. In this talk I discuss how to characterise the genealogy underlying this evolving particle system. More precisely, under certain conditions we can show that the genealogy converges (as the number of particles grows) to Kingman's coalescent, a stochastic tree-valued process widely studied in population genetics. This makes explicit the analogy between sequential Monte Carlo and an evolving biological population. This is joint work with Suzie Brown, Adam Johansen, Jere Koskela, and Dario Spanò. ------------------------------------------------ Il webinar è organizzato dalla "de Castro" Statistics Initiative www.carloalberto.org/stats Cordiali saluti, Pierpaolo De Blasi --- University of Torino & Collegio Carlo Alberto carloalberto.org/pdeblasi <https://sites.google.com/a/carloalberto.org/pdeblasi/>

We show that the alleged negative relation is not robust to the aggregation window, nor to the way the volatility of volume is measured. In particular, when we employ high-frequency one-minute volume data, the relation is positive and robust, restoring economic intuition which commends investors’ aversion to liquidity uncertainty. *Zoom link*: https://us02web.zoom.us/j/81109847151?pwd=TEl0L1lNVEtUbjh5RVJvM3pRUG40UT09 <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/hB0bS22L3Y_ENjUYgp7T2q29i3-4-1d8K-…> Meeting ID: 811 0984 7151 Passcode: 268588 <#> <#> <#> <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/UOaR7QZZ72ijC7nTqdjimVg5pfXen_62Nr…> <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/xNe5dk_6XysCdtcFZgp9tEdEOiDcNPaSPo…> <#> FONDAZIONE COLLEGIO CARLO ALBERTO Piazza Arbarello 8 - 10122 Torino, Italy phone: +390116705000 segreteria(a)carloalberto.org - www.carloalberto.org Facebook <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/aYJaD7KHzPThdS0ChTziuoKxUUel5iGJkU…> Twitter <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/vhWcXWrVH_v7eAq6F84bbGMelwvSuUQT3Q…> LinkedIn <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/dfKa9OGMdhR4lMt-qQMtDhs0uMVON6_UUF…> Instagram <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/FZi5lYdgx-IrtBPfZ_N1VOEbhUdSAHDONW…> Youtube <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/LsxVbQ7peor6-eKyVmNsaiIImZcs_kIZ2U…> <#> *INFORMATION UNDER THE NEW GENERAL DATA PROTECTION REGULATION (GDPR)* Your personal information has been gathered for the exclusive purpose of informing you about the Collegio's initiatives, considering our and your legitimate interest or your consent.

virtual seminar in Insubria & Bicocca
by Emanuela Rosazza Gianin 12 May '21

12 May '21

Dear all, On *May 20 at 17:00, Cosimo-Andrea Munari* (University of Zurich) will give a virtual seminar “in Insubria & Bicocca”, to which you are all invited. You can find the title and abstract below. Title: Capital requirements and claims recovery: A new perspective on solvency regulation Abstract: Protection of creditors is a key objective of financial regulation. Where the protection needs are high, i.e., in banking and insurance, regulatory solvency requirements help prevent creditors from incurring losses on their claims. The current regulatory requirements based on Value at Risk and Expected Shortfall limit the probability of default of financial institutions, but fail to control the size of recovery on creditors' claims in the case of default. We resolve this failure by developing a novel risk measure, Recovery Value at Risk. Our conceptual approach is flexible and allows the construction of general recovery risk measures. By design, these risk measures control recovery on creditors' claims and integrate the protection needs of creditors into the incentive structure of the management. The seminar will be on *Zoom*. You can find the information to join below. Speaker: Cosimo-Andrea Munari (Univ. Zurich) Topic: Capital requirements and claims recovery: A new perspective on solvency regulation Time: May 20, 2021 05:00 PM Rome Where: Zoom Link: https://us02web.zoom.us/j/82132902292?pwd=UlJXcE5mT1dmSmhtKzNkS1pXTlRhUT09 ID riunione: 821 3290 2292 Passcode: 912323 After the talk, you are all invited to remain in the meeting for an informal aperitif and chat.

Online Seminar @SNS, Julien Guyon (Bloomberg L.P.), May 18 2021 at 4 PM (CEST)
by Giulia Livieri 12 May '21

12 May '21

Dear all, Tuesday, May 18 at 4 PM (CEST) there will be the following online seminar. Speaker: Julien Guyon (Bloomberg L.P.); below the short bio. Title: Dispersion-Constrained Martingale Schrodinger Problems and the Joint S&P 500/VIX Smile Calibration Puzzle Abstract: The very high liquidity of S&P 500 (SPX) and VIX derivatives requires that financial institutions price, hedge, and risk-manage their SPX and VIX options portfolios using models that perfectly fit market prices of both SPX and VIX futures and options, jointly. This is known to be a very difficult problem. Since VIX options started trading in 2006, many practitioners and researchers have tried to build such a model. So far the best attempts, which used parametric continuous-time jump-diffusion models on the SPX, could only produce approximate fits. In this talk we solve this long standing puzzle for the first time using a completely different approach: a nonparametric discrete-time model. Given a VIX future maturity T1, we build a joint probability measure on the SPX at T1, the VIX at T1, and the SPX at T2 = T1 + 30 days which is perfectly calibrated to the SPX smiles at T1 and T2, and the VIX future and VIX smile at T1. Our model satisfies the martingality constraint on the SPX as well as the requirement that the VIX at T1 is the implied volatility of the 30-day log-contract on the SPX. The model is cast as the unique solution of what we call a Dispersion-Constrained Martingale Schrodinger Problem which is solved by duality using an extension of the Sinkhorn algorithm, in the spirit of (De March and Henry-Labordere, Building arbitrage-free implied volatility: Sinkhorn's algorithm and variants, 2019). We prove that the existence of such a model means that the SPX and VIX markets are jointly arbitrage-free. The algorithm identifies joint SPX/VIX arbitrages should they arise. Our numerical experiments show that the algorithm performs very well in both low and high volatility environments. Finally, we discuss how our technique extends to continuous-time stochastic volatility models, via what we dub VIX-Constrained Martingale Schrodinger Bridges, inspired by the classical Schrodinger bridge of statistical mechanics. The resulting stochastic volatility model is numerically implemented and is shown to achieve joint calibration with very high accuracy. Time permitting, we will also briefly discuss a few related topics: (i) a remarkable feature of the SPX and VIX markets: the inversion of convex ordering, and how classical stochastic volatility models can reproduce it; (ii) why, due to this inversion of convex ordering, and contrary to what has often been stated, among the continuous stochastic volatility models calibrated to the market smile, the local volatility model does not maximize the price of VIX futures. Short bio: Julien Guyon is a senior quantitative analyst in the Quantitative Research group at Bloomberg L.P., New York. He is also an adjunct professor in the Department of Mathematics at Columbia University and at the Courant Institute of Mathematical Sciences, NYU, and a Louis Bachelier Fellow. Julien serves as an Associate Editor of SIAM Journal on Financial Mathematics, Finance & Stochastics, and Journal of Dynamics and Games, and as a Managing Editor of Quantitative Finance. Before joining Bloomberg, Julien worked in the Global Markets Quantitative Research team at Societe Generale in Paris for six years, and was an adjunct professor at Universite Paris Diderot and Ecole des Ponts ParisTech. Julien co-authored the book Nonlinear Option Pricing (Chapman & Hall, 2014) with Pierre Henry-Labordere. He has published more than 20 articles in peer-reviewed journals (including Finance & Stochastics, SIAM Journal on Financial Mathematics, Quantitative Finance, Risk, Journal of Computational Finance, Annals of Applied Probability, Stochastic Processes and their Applications) and is a regular speaker at international conferences, both academic and professional. His main research interests include nonlinear option pricing, volatility and correlation modeling, (nonlinear) optimal transport, and numerical probabilistic methods. A big soccer fan, Julien has also developed a strong interest in sports analytics, and has published several articles on the FIFA World Cup, the UEFA Champions League, and the UEFA Euro both in academic journals and in top-tier newspapers such as The New York Times, The Times, Le Monde, and El Pais, including a new, fairer draw method for the FIFA World Cup. Some of his suggestions for draws and competition formats have already been adopted by FIFA and UEFA. His paper "Risk of collusion: Will groups of 3 ruin the FIFA World Cup?" won the 2nd prize at the 2021 MIT Sloan Sports Analytics Conference, the biggest sports analytics event in the world.

LTI@Unito/CCA webinar in Quantitative Finance: “Self Inflicted Debt Crises”, Theo Dimpoulos (HEC Lausanne) | May 12, 2021 @12:00
by Luca Regis 07 May '21

07 May '21

Dear Colleagues, I am happy to share with you the following invitation to the Quantative Finance webinar organized by LTI@UniTO and Collegio Carlo Alberto, “Self Inflicted Debt Crises” by Theo Dimopoulos (HEC Lausanne), which will take place on Zoom on May 12, at 12.00. Below you find the Zoom link and an abstract of the presentation. Best regards, Luca Regis <#> <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/4a6SaiafujNub6pHriwakj0wncDAbmtUwm…> <#> LTI@Unito and Fondazione Collegio Carlo Alberto are pleased to invite you to the next webinar <#> *May 12, 2021 | 12:00-13:15* *“Self Inflicted Debt Crises”* *Theo Dimopoulos (HEC Lausanne)* <#> *Abstract*: The restrictions on economic activity in the Covid-19 pandemic have led to a looming debt crisis. In a dynamic model of strategic default and debt renegotiation, we show how to resolve debt crises depending on borrowers’ time-inconsistent preferences. Myopic borrowers misprice their option to default by a U-shaped negative pricing error, which causes imperfect consumption smoothing, underinvestment in normal times, and risk shifting in crisis times. The model shows that bailouts need to be tailored to borrowers’ myopia, that lenders and borrowers ultimately self-inflict debt crises through their strategic interaction, that myopic distress can be cheaper to resolve than rational distress, and that myopia can be beneficial for rational agents. Optimal bailouts either punish or reward myopia through smaller or larger transfers, leading to procrastinated default and protracted crises or the reverse, depending on whether transfers exacerbate or alleviate the borrowers’ misperception of default risk. *Zoom Link*: https://us02web.zoom.us/j/86981911369?pwd=enM0c0lRM1BqOUhiNXJ1b1hoRUFkZz09 <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/hbrUdAY_KcHiYFp-zoUEFWWBp9T0Kg0cUl…> Meeting ID: 869 8191 1369 Passcode: 166986 <#> <#> <#> <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/Kc1f2ufQnOOWcPREh0lKmL7Q4fzC6kZTEu…> <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/b-edRrCQzu0enNR_azA3LGWp3pL_izmv84…> <#> FONDAZIONE COLLEGIO CARLO ALBERTO Piazza Arbarello 8 - 10122 Torino, Italy phone: +390116705000 segreteria(a)carloalberto.org - www.carloalberto.org Facebook <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/Gt2401hi4FK-WGDLZAuu96sNqvjzd4A07j…> Twitter <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/dMAP2G9V5OGEVQgiZTVGvRpJC3GmNfL6Kc…> LinkedIn <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/ZfldktwuWczKYK5tZjUQN--QuFGPkzyS3J…> Instagram <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/lxHhxw7_pN8bfa4lRN1Ro0KNXDKFYNSqGI…> Youtube <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/toZ5omiJqAM-e_mmWMFepsHZKCAJ2-Skq2…> <#> *INFORMATION UNDER THE NEW GENERAL DATA PROTECTION REGULATION (GDPR)* Your personal information has been gathered for the exclusive purpose of informing you about the Collegio's initiatives, considering our and your legitimate interest or your consent.

Pisa Online Seminars - Michael Högele and Alessandra Caraceni (Tuesday, May 11 at 16:00 and 17:00)
by Giacomo Filippo Di Gesu 06 May '21

06 May '21

Dear colleagues, I would like to invite you to the following online seminar organized by the Probability group of the University of Pisa. The two talks will be accessible under the link Click here to join<https://teams.microsoft.com/l/meetup-join/19:af3d635091e049579e555a84219ab3…"Tid":"c7456b31-a220-47f5-be52-473828670aa1","Oid":"dfd1e5f6-331d-43e0-a180-4bb6ce727fb7"}> Best regards, Giacomo Tuesday, May 11, 16:00 Speaker: Michael Högele (Universidad de los Andes) Title: Cutoff thermalization for Ornstein-Uhlenbeck systems with small Lévy noise in the Wasserstein distance Abstract: This talk presents recent results on cutoff thermalization (also known as the cutoff phenomenon) for a general class of asymptotically exponentially stable Ornstein-Uhlenbeck systems under ε-small additive Lévy noise. The driving noise processes include Brownian motion, α-stable Lévy flights, finite intensity compound Poisson processes and red noises and may be highly degenerate. Window cutoff thermalization is shown under generic mild assumptions, that is, we see an asymptotically sharp ∞/0-collapse of the renormalized Wasserstein distance from the current state to the equilibrium measure μ^ε along a time window centered in a precise ε-dependent time scale t_ε . In many interesting situations such as reversible (Lévy) diffusions it is possible to prove the existence of an explicit, universal, deterministic cutoff thermalization profile. The existence of this limit is characterized by the absence of non-normal growth patterns in terms of an orthogonality condition on a computable family of generalized eigenvectors of the matrix Q. With this piece of theory at hand this article provides a complete discussion of the cutoff phenomenon for the classical linear oscillator with friction subject to ε-small Brownian motion or α-stable Lévy flights. Furthermore, we cover the highly degenerate case of a linear chain of oscillators in a generalized heat bath at low temperature. Tuesday, May 11, 17:00 Speaker: Alessandra Caraceni (University of Oxford) Title: Polynomial mixing time for edge flips on planar maps Abstract: A long-standing problem proposed by David Aldous consists in giving a sharp upper bound for the mixing time of the so-called “triangulation walk”, a Markov chain defined on the set of all possible triangulations of the regular n-gon. A single step of the chain consists in performing a random edge flip, i.e. in choosing an (internal) edge of the triangulation uniformly at random and, with probability 1/2, replacing it with the other diagonal of the quadrilateral formed by the two triangles adjacent to the edge in question (with probability 1/2, the triangulation is left unchanged). While it has been shown that the relaxation time for the triangulation walk is polynomial in n and bounded below by a multiple of n^{3/2}, the conjectured sharpness of the lower bound remains firmly out of reach in spite of the apparent simplicity of the chain. For edge flip chains on different models – such as planar maps, quadrangulations of the sphere, lattice triangulations and other geometric graphs – even less is known. We shall discuss results concerning the mixing time of random edge flips on rooted quadrangulations of the sphere obtained in joint work with Alexandre Stauffer. A “growth scheme” for quadrangulations, which generates a uniform quadrangulation of the sphere by adding faces one at a time at appropriate random locations, can be combined with careful combinatorial constructions to build probabilistic canonical paths in a relatively novel way. This method has implications for a range of interesting edge-manipulating Markov chains on so-called Catalan structures, from “leaf translations” on plane trees to “edge rotations” on general planar maps. ************************ Giacomo Di Gesù Dipartimento di Matematica Università di Pisa Largo Bruno Pontecorvo 5 56127 - Pisa, Italy giacomo.digesu(a)unipi.it<mailto:giacomo.digesu@unipi.it> https://sites.google.com/site/giacomodigesu/

Seminar Aernout van Enter
by Massimo Campanino 05 May '21

05 May '21

Aernout van Enter ONE-SIDED VERSUS TWO-SIDED STOCHASTIC PROCESSES Thursday the 6th of May 3 pm (Italian time) Stochastic processes can be parametrised by time (such as occurs in Markov chains), in which case conditioning is one-sided (on the past) or by one-dimensional space (which is the case, for example, for one-dimensional Markov fields), where conditioning is two-sided (on the right and on the left). I will discuss some examples, in particular generalising this distinction to g-measures versus Gibbs measures, where, instead of a Markovian dependence, the weaker property of continuity (in the product topology) is considered. In particular I will discuss when the two descriptions (one-sided or two-sided) produce the same objects and when they are different. We show moreover the role one-dimensional entropic repulsion plays in this setting. Based on joint work with R. Bissacot, E. Endo and A. Le Ny, and S.

Fwd: [owps] OWPS: talks tomorrow
by Faggionato, Alessandra 05 May '21

05 May '21

Buongiorno giro l'annuncio del OWPS di domani. Saluti Alessandra ---------- Forwarded message --------- Da: One World Probability <ow.probability(a)gmail.com> Date: mer 5 mag 2021 alle ore 08:12 Subject: [owps] OWPS: talks tomorrow To: <owps(a)lists.bath.ac.uk> Dear All, we have two talks tomorrow. Remember that we start 14:00 UTC which is 16:00 CET! 14:00-15:00 UTC Christina Goldschmidt The stable graph: the scaling limit of critical random graphs with i.i.d. random degrees having power-law tails Abstract: Consider a graph with label set \{1,2, \ldots,n\} chosen uniformly at random from those such that vertex i has degree D_i, where D_1, D_2, \ldots, D_n are i.i.d. strictly positive random variables. The condition for criticality (i.e. the threshold for the emergence of a giant component) in this setting is E[D^2] = 2 E[D], and we assume additionally that P(D = k) \sim c k^{-(\alpha + 2)} as k tends to infinity, for some \alpha \in (1,2). In this situation, it turns out that the largest components have sizes on the order of n^{\alpha/(\alpha+1)}. Building on earlier work of Adrien Joseph, we show that the components have scaling limits which can be related to a forest of stable trees (à la Duquesne-Le Gall-Le Jan) via an absolute continuity relation. This gives a natural generalisation of the scaling limit for the Erd\H{o}s-Renyi random graph (obtained in collaboration with Louigi Addario-Berry and Nicolas Broutin a few years ago, extending results of Aldous), which we call the stable graph. This complements recent work on random graph scaling limits by various authors including Bhamidi, Broutin, Duquesne, van der Hofstad, van Leeuwaarden, Riordan, Sen, M. Wang and X. Wang. 15:00 - 16:00 UTC Bénédicte Haas Distributional properties of the stable graphs Abstract: In this talk we will investigate some distributional properties of the connected components of the stable graphs introduced by Christina in the previous talk. We recall that for $\alpha \in (1,2]$, the $\alpha$-stable graph arises as the universal scaling limit of critical random graphs with i.i.d. degrees having an $\alpha$-dependent power-law tail behavior. Consider a connected component of such a graph. Our aim will be: (1) to describe the distribution of its kernel and more generally of its discrete finite-dimensional marginals, (2) to explicit its distribution as a collection of $\alpha$-stable trees glued on the kernel, and (3) present a line-breaking construction, in the same spirit as Aldous’ line-breaking construction of the Brownian CRT.

International Conference in Venice - CALL FOR PAPERS
by Monica Billio 04 May '21

04 May '21

20th INTERNATIONAL CONFERENCE CREDIT 2021 *Compound Risk: Climate, Disaster, Finance, Pandemic * Venice, Italy 23 –24 September 2021 * * *GRETA Associati* (Venice, Italy), *Cattolica Assicurazioni* (Verona, Italy), *European Datawarehouse *(Frankfurt, Germany), *European Investment Bank* (Luxembourg), *European Investment Fund *(Luxembourg) and *Intesa Sanpaolo *(Milan, Italy) are co-sponsors of a Conference to be held in Venice on September 23-24, 2021. The Conference CREDIT 2021 will bring together academics, practitioners and PhD students working in various areas of financial and credit risk with the aim to create a unique opportunity for participants to discuss research progress and policy and industry-relevant insights as well as directions for future research. Credit 2021 is the *twentieth *in a series of events dedicated to various aspects of credit risk and organised under the auspices of the *Department of Economics* and *VERA - Venice centre in Economic and Risk Analytics for public policies - of the Ca’ Foscari University of Venice*, *ABI - Italian Banking Association*,***AIAF - Associazione Italiana per l'Analisi Finanziaria* and the *Joint Research Center, European Commission* (Ispra, Italy). The theme of this year’s conference is the relation between financial risk on the one hand and pandemic, climate and disaster risk, on the other hand, with particular attention to the possible compounding of different sources of risk. The past year, 2020, has been marked by the still-ongoing COVID-19 pandemic crisis, which has shown how fragile our economic systems can be when confronted with shocks that threaten public health and the closeness of the connections between economic and financial risks and public policy. Climate change is now widely recognized as a new source of financial risk which is relevant both at the level of households and individual institutions and the systemic level. In particular, the many central banks and financial institutions that have joined the Network for Greening the Financial System (NGFS) have issued recommendations on how to integrate climate considerations into risk management strategies and practices. However, risks such as pandemics and climate change do not occur in isolation but can also compound, as has already been seen in several countries. The compounding of risk, which is currently poorly understood, increases the complexity of risk assessment and risk management, and it has implications for socio-economic development, as well as for public debt sustainability. In the EU, these aspects have major implications for efforts to increase the resilience of the economy to future shocks and to “build back better”, and requires the alignment of COVID-19 recovery policies, such as those supported by the NextGenerationEU, and the EU Green Deal and the Paris Agreement targets. The organizers of CREDIT 2021 encourage submissions on a range of topics of relevance to this year’s theme including: finance and COVID-19; finance and climate risks; finance and compound COVID-19 and climate risks. In particular, submissions are welcome in the following areas: • INVESTMENTS: Sustainable Finance, Disaster risk finance; Finance 4 good; public finance; blended finance. • POLICIES: Climate Policies, European Green New Deal; Next Generation EU; Recovery Plan. • INFORMATION: Data gaps; modelling challenges; risk transmission channels; uncertainty; complexity. The final program will include both submitted and invited papers. Acceptances received so far from invited speakers include *Vittoria Colizza *(INSERM, France), *Robert Engle *(Stern Business School, New York University) and *Roberto Rigobon* (MIT Sloan School of Management) who will deliver keynotes, respectively on finance and on epidemics. The Conference will also feature panel discussions on researchers', practitioners' and policy makers’ views of the major issues at stake. The SCIENTIFIC COMMITTEE for the Conference consists of: • * Stefano Battiston *(Ca’ Foscari University of Venice & University of Zurich, Programme Chair) • * Monica Billio *(Ca’ Foscari University of Venice & GRETA) • * Francesca Campolongo *(Joint Research Center, European Commission) • *Vittoria Colizza* (INSERM, France) • * Helmut Kraemer-Eis* (European Investment Fund) • * Jan Pieter Krahnen* (Leibniz Institute for Financial Research SAFE & Goethe University, Frankfurt) • *Irene Monasterolo *(Vienna University of Economics and Business) • *Steven Ongena* (University of Zurich, Swiss Finance Institute, KU Leuven & CEPR) • *Roberto Rigobon* (MIT Sloan School of Management) • *Stephen Schaefer* (London Business School) CALL FOR PAPERS Those wishing to present a paper at the Conference should submit by *May 31, 2021 *to the address given below (preferably in electronic format).

(PMS)^2 online talk: Guangqu Zheng, Monday May 10 at 17:30
by Maurizia Rossi 03 May '21

03 May '21

Dear colleagues, We are happy to announce the following online talk: Speaker: *Guangqu Zheng* (University of Kansas) Title: *Malliavin derivatives of hyperbolic Anderson model with applications to its absolute continuity and spatial averages.* Date and time: *Monday May 10, 17:30-18:30 (Rome time zone)* Abstract: see below. Zoom link: https://us02web.zoom.us/j/83843864962?pwd=NlNadHhIRkdzYUErZWJpbTNJaytDUT09 Meeting ID: 838 4386 4962 Passcode: 5gVVXb This talk is the second of the *(PMS)^2: Pavia-Milano Seminar series on Probability and Mathematical Statistics* organized jointly by the universities Milano-Bicocca, Pavia, Milano-Politecnico and Milano-Statale. Participation is free and welcome! (though limited to 100 participants for technical reasons) Best regards The organizers (Mario Maurelli, Carlo Orrieri, Maurizia Rossi, Margherita Zanella) *Abstract:* In this talk, we present recent work on the hyperbolic Anderson model driven by a space-time colored Gaussian homogeneous noise with spatial dimension one and two. Under mild assumptions, we provide Lp-estimates of the iterated Malliavin derivatives of the solution in terms of the fundamental solution of the wave solution. We present two applications: (1) We present quantitative central limit theorems for spatial averages of the solution to the hyperbolic Anderson model, where the rates of convergence are described by the total variation distance. These quantitative results have been elusive so far due to the temporal correlation of the noise blocking us from using the Itô calculus. (2) We establish the absolute continuity of the law for the hyperbolic Anderson model. The Lp-estimates of Malliavin derivatives are crucial ingredients to verify a local version of Bouleau-Hirsch criterion for absolute continuity. Our approach substantially simplifies the arguments for the one-dimensional case, which has been studied in the recent work by Balan, Quer-Sardanyons and Song (2019). This talk is based on the joint work (arXiv:2101.10957) with *R. Balan*, *D. Nualart* and *L. Quer-Sardanyons* (2021). - - - Maurizia Rossi Dipartimento di Matematica e Applicazioni Università di Milano-Bicocca

Seminar Antonio Linero @Bocconi - May 6th
by Giacomo Zanella 03 May '21

03 May '21

We announce the following DEC Statistics webinar at Bocconi: Date: Thursday, May 6, h17:00 (Italy time) Speaker: Antonio Linero (UT Austin) Title: Bayesian Decision Tree Ensembling Strategies for Nonparametric Problems Abstract: In this talk we will make the case for using Bayesian decision tree ensembles, such as Bayesian additive regression trees (BART), for addressing some fully-nonparametric problems. We present models for density regression and survival analysis, and argue that our approaches are both easier to use and more effective than more standard Bayesian nonparametric solutions (such as those based on mixture models). On the applied side, we show how to use our models to extract interesting features across several datasets. On the theoretical side, we also show that our models attain minimax-optimal rates of convergence of the posterior in high-dimensional settings. Throughout the talk, we will emphasize the flexibility and ease-of-use of our approach: all simulation and real data analyses attain excellent results using heuristically chosen "default" priors, and it is quite straight-forward for researchers (both in-principle and in-practice) to embed our ensembles in larger models. The webinar will be on zoom at: https://zoom.us/j/95265599865?pwd=NlEwVWFjNktjNkx5VjZFZmFLVGh0UT09 Meeting ID: 952 6559 9865 Passcode: 634366 Kind regards, Giacomo Zanella

Buongiorno, giro l'annuncio del OWPS per chi fosse interessato. Saluti Alessandra ---------- Forwarded message --------- Da: One World Probability <ow.probability(a)gmail.com> Date: mer 28 apr 2021 alle ore 14:04 Subject: [owps] talks tomorrow april 29 To: <owps(a)lists.bath.ac.uk> Dear All, we have two talks tomorrow. Remember that we start 14:00 UTC which is 16:00 CET! 14:00-15:00 UTC Bastien Mallein Tail behaviour of the derivative martingale in a branching random walk A branching random walk is a discrete-time particle system on the real line in which every particle gives independently birth to offspring positioned around the position of their parent. The derivative martingale of the branching random walk is a stochastic process which allows to measure the number of particles traveling at maximal speed in this process. Under some general integrability conditions uncovered by Aïdékon (2013) and Chen (2015), we know the derivative martingale converges a.s. to a non-negative limit. Recently, Maillard and Pain (2019) obtained a necessary and sufficient condition on the reproduction law of the branching Brownian motion under which the convergence of the derivative martingale satisfies a specific central limit theorem. In this talk, based on a joint work with Alexander Iksanov and Dariusz Buraczewski, we extend their result to branching random walk settings. The proof is based on the characterization of subharmonic functions of the killed random walk with at most linear growth. 15:00 - 16:00 UTC Hui He Deviation probabilities for the maximum of a branching random walk. Consider a supercritical branching random walk on real line started from the origin. Under some mild conditions, it is proved by Aïdékon (2013) that its centered maximum converges in law. In this talk, we will review some recent results on the large/lower deviation probabilities of the maximum. The talk is based on joint works with Xinxin Chen and Bastien Mallein.

Seminar Aernout van Enter
by Massimo Campanino 28 Apr '21

28 Apr '21

Aernout van Enter ONE-SIDED VERSUS TWO-SIDED STOCHASTIC PROCESSES Thursday the 6th of May 3 pm (Italian time) Stochastic processes can be parametrised by time (such as occurs in Markov chains), in which case conditioning is one-sided (on the past) or by one-dimensional space (which is the case, for example, for one-dimensional Markov fields), where conditioning is two-sided (on the right and on the left). I will discuss some examples, in particular generalising this distinction to g-measures versus Gibbs measures, where, instead of a Markovian dependence, the weaker property of continuity (in the product topology) is considered. In particular I will discuss when the two descriptions (one-sided or two-sided) produce the same objects and when they are different. We show moreover the role one-dimensional entropic repulsion plays in this setting. Based on joint work with R. Bissacot, E. Endo and A. Le Ny, and S.

Padova Online Seminar by Gioia Carinci (Università di Modena e Reggio Emilia) [Friday, May 7 at 14.30]
by alessandra bianchi 28 Apr '21

28 Apr '21

Dear Colleagues, We would like to invite you to the following Probability seminar that will take place on May 7 at 14.30 by the zoom platform. ________________________________________________________ Speaker: Gioia Carinci (Università di Modena e Reggio Emilia) Title: Condensation of SIP particles and sticky Brownian motion 7 MAY (Friday) - 14:30 zoom link: TBA available on the webpage https://www.math.unipd.it/~bianchi/seminari/ ) Abstract: The symmetric inclusion process (SIP) is a particle system with attractive interaction. We study its behavior in the condensation regime attained for large values of the attraction intensity. Using Mosco convergence of Dirichlet forms, we prove convergence to sticky Brownian motion for the distance of two SIP particles. We use this result to obtain, via duality, an explicit scaling for the variance of the density field in this regime, for the SIP initially started from a homogeneous product measure. This provides relevant new information on the coarsening dynamics of condensing particle systems on the infinite lattice. Joint works with M. Ayala, C Giardina and F.

by c.ceci＠unich.it 26 Apr '21

26 Apr '21

Buongiorno a tutti, abbiamo il piacere di annunciare il quarto appuntamento del ciclo di seminari online promosso dal Gruppo UMI PRISMA. May 3,2021 - 16:00-17:00 (CET) Francesca Biagini Reduced-form setting under model uncertainty with non-linear affine Intensities. - 17:00-18:00 (CET) Katia Colaneri Classical solutions of the Backward PIDE for Markov modulated Marked Point Processes and applications to catastrophic bonds. Abstract Francesca Biagini: In this talk we present a market model including financial assets and life insurance liabilities within a reduced-form framework under model uncertainty by following [1]. In particular we extend this framework to include mortality intensities following an affine process under parameter uncertainty, as defined in [2].This allows both to introduce the definition of a longevity bond under model uncertainty in a consistent way with the classical case under one prior, as well as to compute it by explicit formulas or by numerical methods. We also study conditions to guarantee the existence of a càdlàg modification for the longevity bond’s value process. Furthermore, we show how the resulting market model extended with the longevity bond is arbitrage-free and study arbitrage-free pricing of contingent claims or life insurance liabilities in this setting. This talk is based on: [1] Francesca Biagini and Yinglin Zhang. Reduced-form framework under model uncertainty. The Annals of Applied Probability, 29(4):2481–2522, 2019. [2] Francesca Biagini and Katharina Oberpriller. Reduced-form framework under model uncertainty. Preprint University of Munich and Gran Sasso Science Institute, 2020. [3] Tolulope Fadina, Ariel Neufeld, and Thorsten Schmidt. Affine processes under parameter uncertainty. Probability, Uncertainty and Quantitative Risk <https://link.springer.com/journal/41546> volume 4 (5), 2019. Abstract Katia Colaneri: We give conditions ensuring that the backward partial integro differential equation (PIDE) associated with a multidimensional jump-diffusion with a pure jump component has a unique classical solution. Our proof uses a probabilistic arguments and extends the results of (Pham 1998) to processes with a pure jump component where the jump intensity is modulated by a diffusion process. This result is particularly useful in some applications to pricing and hedging of financial and actuarial instruments, and we provide an example to pricing of catastrophic (CAT) bonds.

by Fabrizio Lillo 25 Apr '21

25 Apr '21

*Wednesday April 28 at 4pm (CEST):* Petter Kolm (NYU, Courant Institute) *Title*: Feature Selection in Jump Models *Abstract*: Jump models switch infrequently between states to fit a sequence of data while taking the ordering of the data into account. In this talk, we propose a new framework for joint feature selection, parameter and state-sequence estimation in jump models. Feature selection is necessary in high-dimensional settings where the number of features is large compared to the number of observations and the underlying states differ only with respect to a subset of the features. We develop and implement a coordinate descent algorithm that alternates between selecting the features and estimating the model parameters and state sequence, which scales to large data sets with large numbers of (noisy) features. We demonstrate the usefulness of the proposed framework by comparing it with a number of other methods on both simulated and real data in the form of financial returns, protein sequences, and text. The resulting sparse jump model outperforms all other methods considered and is remarkably robust to noise.

Thursday, 29 April, 17:00 CEST *Carri Chan,* Columbia University Prediction-Driven Surge Planning with Applications in the Emergency Department <http://mailsender.luiss.it/lists/lt.php?id=cRpQBwwLSAULAAdOVgFdBQs> Optimizing emergency department (ED) nurse staffing decisions to balance the quality of service and staffing cost can be extremely challenging, especially when there is a high level of uncertainty in patient-demand. Increasing data availability and continuing advancements in predictive analytics provide an opportunity to mitigate demand-rate uncertainty by utilizing demand forecasts. In this work, we study a two-stage prediction framework that is synchronized with the base (made months in advance) and surge (made nearly real-time) staffing decisions in the ED. We quantify the benefit of the more expensive surge staffing. We also propose a near-optimal two-stage staffing policy that is straightforward to interpret and implement. Lastly, we develop a unified framework that combines parameter estimation, real-time demand forecasts, and staffing in the ED. High fidelity ED simulation experiments demonstrate that the proposed framework can reduce staffing costs by 8% – 17% while guaranteeing timely access to care. Joint work with Jing Dong and Yue Hu.

It is easy to implement and computationally efficient. Despite its popularity and successful applications, its theoretical properties have not been fully understood. We show that spectral clustering is minimax optimal in the Gaussian Mixture Model with isotropic covariance matrix, when the number of clusters is fixed and the signal-to-noise ratio is large enough.

Dear colleagues, I would like to invite you to the following online seminar organized by the Probability group of the University of Pisa. The talk will be accessible under the link Click here to join<https://teams.microsoft.com/l/meetup-join/19:af3d635091e049579e555a84219ab3…"Tid":"c7456b31-a220-47f5-be52-473828670aa1","Oid":"dfd1e5f6-331d-43e0-a180-4bb6ce727fb7"}> Best regards, Giacomo Tuesday, April 27, 16:00 Speaker: Constanza Rojas-Molina (CY Cergy Paris Université) Title: (Fractional) random Schrödinger operators, integrated density of states and localization Abstract: We consider the continuous Schrödinger operator - d^2/d^x^2 + B’(x) on the interval [0,L] where the potential B’ is a white noise. We study the entire spectrum of this operator in the large L limit. We prove the joint convergence of the eigenvalues and of the eigenvectors and describe the limiting shape of the eigenvectors for all energies. When the energy is much smaller than L, we find that we are in the localized phase and the eigenvalues are distributed as a Poisson point process. The transition towards delocalization holds for large eigenvalues of order L. In this regime, we show the convergence at the level of operators. The limiting operator in the delocalized phase is acting on R^2-valued functions and is of the form ``J \partial_t + 2*2 noise matrix'' (where J is the matrix ((0, -1)(1, 0))), a form appearing as a conjecture by Edelman Sutton (2006) for limiting random matrices.

(PMS)^2 online talk: Zdzislaw Brzezniak, Monday April 26 at 17:30
by Mario Maurelli 21 Apr '21

21 Apr '21

Dear colleagues, We are happy to announce the following online talk: Speaker: *Zdzislaw Brzezniak* (University of York, UK) Title: *The stochastic Strichartz estimates and stochastic nonlinear Schrödinger equations driven by Levy noise* Date and time: *Monday April 26, 17:30-18:30 (Rome time zone)* Abstract: see below Zoom link: https://us02web.zoom.us/j/87131794820?pwd=R3l0VEtpZXNzUmQ1bnlnbWhBUm5XQT09 Meeting ID: 871 3179 4820 Passcode: 5yFGwK This talk is the first of the *(PMS)^2: Pavia-Milano Seminar series on Probability and Mathematical Statistics* organized jointly by the universities Milano-Bicocca, Pavia, Milano-Politecnico and Milano-Statale. The series will run approximately every fortnight and, for the moment, will be held online. Participation is free and welcome! (though limited to 100 participants for technical reasons) Best regards The organizers (Mario Maurelli, Carlo Orrieri, Maurizia Rossi, Margherita Zanella) Abstract: We establish a new version of the stochastic Strichartz estimate for the stochastic convolution driven by jump noise which we apply to the stochastic nonlinear Schrodinger equation with nonlinear multiplicative jump noise in the Marcus canonical form. With the help of the deterministic Strichartz estimates, we prove the existence and uniqueness of a global solution to stochastic nonlinear Schrodinger equation in $L^2(R^n)$ with either focusing or defocusing nonlinearity in the full subcritical range of exponents as in the deterministic case. This talk will be based on a joint paper with Wei Liu and Jiahui Zhu.

Seminar Pierre Alquier @Bocconi - April 22
by Giacomo Zanella 21 Apr '21

21 Apr '21

A reminder of the following BIDSA webinar (link <https://www.bidsa.unibocconi.eu/wps/wcm/connect/site/bidsa/home/news_events…> ): Date: Thursday, April 22, h14:00 (Italy time) Speaker: Pierre Alquier (RIKEN) Title: Robust Estimation via M.M.D. Minimization Abstract: In this talk, I will study the properties of parametric estimators based on the Maximum Mean Discrepancy (MMD) defined by Briol et al. (2019). In a first time, I will show that these estimators are universal in the i.i.d setting: even in case of misspecification, they converge to the best approximation of the distribution of the data in the model, without ANY assumption on this model. This leads to very strong robustness properties. In a second time,I will show that these results remain valid when the data is not independent, but satisfy instead a weak-dependence condition. This condition is based on a new dependence coefficient, which is itself defined thanks to the MMD. I will show through examples that this new notion of dependence is actually quite general. Reference: This talk is based on the following papers and softwares, with Badr-Eddine Chérief Abdellatif (Oxford University), Mathieu Gerber(University of Bristol), Jean-David Fermanian (ENSAE Paris) and Alexis Derumigny (University of Twente): http://arxiv.org/abs/1912.05737 http://proceedings.mlr.press/v118/cherief-abdellatif20a.html http://arxiv.org/abs/2006.00840 https://arxiv.org/abs/2010.00408 https://cran.r-project.org/web/packages/MMDCopula/ The webinar will be on zoom at: https://zoom.us/j/95795747882 Meeting ID: 957 9574 7882 Passcode: 025765 Kind regards, Giacomo Zanella

(Reminder) Seminar Thursday 22 - Optimal constrained and unconstrained subgraph structures (prof. Clara Stegehuis)
by Gianmarco Bet 21 Apr '21

21 Apr '21

Dear colleagues, This is a reminder that tomorrow (Thursday 22) at 14:30, prof. Clara Stegehuis (Twente University) will give a virtual seminar “in Florence”, to which you are all invited. You can find title and abstract below this message. The seminar will be on Zoom. You can find the information to join below. If you know of someone who might be interested and is not subscribed to the random mailing list, please do not hesitate to forward this announcement to them. Kind regards, Gianmarco Topic: Clara Stegehuis - Optimal constrained and unconstrained subgraph structures Time: Apr 22, 2021 02:30 PM Rome Join Zoom Meeting https://us02web.zoom.us/j/85651690146?pwd=ZnRCbGR6OUlxM2J4RldJd2R1aVE3Zz09 <https://us02web.zoom.us/j/85651690146?pwd=ZnRCbGR6OUlxM2J4RldJd2R1aVE3Zz09> Meeting ID: 856 5169 0146 Passcode: 770134 Title: Optimal constrained and unconstrained subgraph structures Abstract: Subgraphs contain important information about network structures and their functions. We investigate the presence of subgraphs in a random graph model with infinite-variance degrees. We introduce an optimization problem which identifies the dominant structure of any given subgraph. The unique optimizer describes the degrees of the vertices that together span the most likely subgraph and allows us to count and characterize the asymptotic number of subgraphs in a simple manner. We then show that this optimization problem easily extends to investigating other random network structures, such as clustering, which expresses the probability that two neighbors of a vertex are connected. The optimization problem is able to find the behavior of network subgraphs in a wide class of random graph models. ---------------------------------------------------------------------- Gianmarco Bet (he/him) Junior researcher https://gianmarco.bet Phone: (+39) 055 2751491 Department of Mathematics and Informatics "U.

20 Apr '21

Dear colleagues, it is our pleasure to invite you to the following online seminar: Zoom link (see also details below): <https://us02web.zoom.us/j/88398874167?pwd=YkRzdlNYWjVjUlc3T294ZjZuVHNSdz09> https://us02web.zoom.us/j/88398874167?pwd=YkRzdlNYWjVjUlc3T294ZjZuVHNSdz09 Speaker: <https://homepage.univie.ac.at/sara.svaluto-ferro/> Sara Svaluto-Ferro (University of Vienna) Title: From signature-based models to affine and polynomial processes and back. Time: Tuesday, April 27, 4PM (Italian time) Abstract: Modern universal classes of dynamic processes, based on neural networks or signature methods, have recently entered the field of stochastic modeling, in particular in Mathematical Finance. This has opened the door to more data-driven and thus more robust model selection mechanisms, while principles like no arbitrage still apply. We analyze here different types of signature models. In the first part, we focus on models based on the signature of a supporting process, which can range from a Brownian motion, to a multidimensional Levy-process, to a general multidimensional tractable stochastic process, to the times series corresponding to some liquid objects on the market. We also present methods how to fit these models to data. In the second part we focus on signature SDEs, i.e. (possibly Lévy driven) SDEs whose characteristics are linear functions of the process signature. We show how these new models can be embedded in the framework of affine and polynomial processes, which have been - due to their tractability - the dominating process class prior to the new era of highly overparametrized dynamic models. We show that generic classes of diffusion models can be described in terms of a signature SDEs. This allows to get power series expansions for expected values of analytic functions of the process' marginals. The talk is based on joint works with Christa Cuchiero, Guido Gazzani, Francesca Primavera and Josef Teichmann. Zoom meeting details: meeting ID: 883 9887 4167 Passcode: mVJ6SR Best, Matteo Burzoni

19 Apr '21

Care colleghe e colleghi, vi invio l'annuncio del seminario di Vladislav Vysotskiy il 26 aprile a mezzogiorno. Le persone interessate possono ottenere il link contattando l'organizzatrice, Dr Minmin Wang (minmin.wang(a)sussex.ac.uk) Cordiali saluti, Enrico Scalas -- Next Monday (26th April) at 11am (UK time) there’ll be an online probability seminar given by Vladislav Vysotskiy. Title: How long is the convex minorant of a one-dimensional random walk? Abstract: We prove distributional limit theorems for the length of the largest convex minorant of a one dimensional random walk with independent identically distributed increments. Depending on the distribution of the increments there are several regimes with different limit distributions for the length. The most prominent of our results is a central limit theorem for the length in the case when the increments have zero mean and finite variance. Among other tools, we employ a representation of convex minorants of random walks in terms of uniform random permutations. This talk is based on a joint work with Gerold Alsmeyer, Zakhar Kabluchko, and Alexander Marynych.

Corso SIMULATION AND INFERENCE IN POPULATION GENETICS
by Matteo Ruggiero 19 Apr '21

19 Apr '21

Cari colleghi, nell’ambito del programma di Visiting Professors della Laurea Magistrale in Stochastics and Data Science dell’Università di Torino (programma completo alla pagina https://www.master-sds.unito.it/go/visiting) con piacere annunciamo il seguente corso: -------------------------------------- Paul JENKINS (University of Warwick, UK) SIMULATION AND INFERENCE IN POPULATION GENETICS Population genetics provides a rich source of data. We now have the ability to sequence, cost-efficiently, the genomes of a large number of individuals from a species. Patterns of variation in DNA sequences offer a rich insight into biological and demographic processes: mutation, natural selection, past migration events, admixture, population structure, and so on. But such data are high-dimensional, noisy, and - because of shared ancestry - not independent, giving rise to some challenging statistical problems. In this course we will cover two important models for the analysis of genetic data - the coalescent, and the Wright-Fisher diffusion. We will discuss methods of simulation of data from these models, as well as how to perform inference for key biological and evolutionary parameters, using techniques such as MCMC. -------------------------------------- Il corso si svolgerà online secondo il seguente calendario - mar 27 Aprile, h.14-16 - mer 28 Aprile, h.16-18 - mar 4 Maggio, h.14-16 - mer 5 Maggio, h.16-18 - mer 12 Maggio, h.16-18 - mar 18 Maggio, h.14-16 - mer 19 Maggio, h.16-18 Il corso è rivolto agli studenti della Laurea Magistrale ma la partecipazione è aperta a tutti gli interessati, tramite le seguenti riunioni Webex valide rispettivamente per le lezioni del martedì e del mercoledì: https://unito.webex.com/unito/j.php?MTID=meeb9bd7865e8bc86b75074b346c0a3ed Ricorre ogni Martedì con validità 13/4/2021 fino a 18/5/2021 da 14:00 a 16:00 Numero riunione: 121 415 2525 Password: MEiAMZMf986 https://unito.webex.com/unito/j.php?MTID=m775c416c6142fd5b86bd7207f46dbabe Ricorre ogni Mercoledì con validità 14/4/2021 fino a 19/5/2021 da 16:00 a 18:00 Numero riunione: 121 469 7803 Password: C5RsPRapS92 Cordiali saluti, Matteo Ruggiero --- Matteo Ruggiero University of Torino and Collegio Carlo Alberto www.matteoruggiero.it

Course ISI-ERS "An Introduction to Functional Data Analysis for Density Functions in Bayes spaces"
by Alessandra Menafoglio 19 Apr '21

19 Apr '21

We cordially invite you to the short course "An Introduction to Functional Data Analysis for Density Functions in Bayes spaces”, which will be held on 29-30 April 2021, both days from 14:00 alle 17:00 (GMT+2). The course is part of the initiatives of the International Statistical Institute (ISI-ERS). It aims to provide participants with an overview on the models and methods today available for the analysis of distributional data (e.g., probability densities) by using the geometry of Bayes spaces. Further information on the course is available at: https://iasc-isi.org/events/iasc-ers-course-an-introduction-to-functional-d… <https://iasc-isi.org/events/iasc-ers-course-an-introduction-to-functional-d…> Participation to the webinars is free of charge, but registration is requested using the link below: https://register.gotowebinar.com/register/8667082239416059148 <https://register.gotowebinar.com/register/8667082239416059148> Best regards, Alessandra Menafoglio Karel Hron Jitka Machalova **Abstract** The analysis of distributional data (probability density functions or histogram data) has recently gained increasing attention in the applications. Distributional data are often observed by themselves, or as result of aggregation of large streams of data. The course will provide an introduction to the analysis of these data using a Functional Data Analysis (FDA) approach, grounded on the perspective of Bayes spaces. These spaces are mathematical spaces whose points are densities (or, more generally, measures), which generalize to the FDA setting the Aitchison simplex for multivariate compositional data. The course will give an overview of the theory of Bayes spaces, as well as of statistical methods developed in this setting. All the methods will be illustrated through examples from real case studies. — Alessandra Menafoglio MOX - Dept. of Mathematics Politecnico di Milano Piazza Leonardo da Vinci, 32, 20133 Milan - Italy Phone: +39 02 2399 4642 Email: alessandra.menafoglio(a)polimi.it

Best regards, Raffaella Carbone *Cambyse Rouzé - Title and abstract* Title: Complete modified logarithmic Sobolev inequalities and quantum Gibbs samplers Abstract: Since the seminal works of Dobrushin-Shlosman and Stroock-Zegarlinski, equilibrium and out-of-equilibrium properties of classical lattice spin systems are known to be closely related: given a potential, one can construct a Markov process, called Glauber dynamics, whose reversing state coincides with the Gibbs state for the given potential. For these dynamics, Holley and Stroock made the key observation that systems thermalizing in times scaling logarithmically in the system size, a property known as rapid mixing, satisfy exponential decay of correlations at equilibrium. The converse implication, namely that exponential decay of correlations implies rapid mixing, was investigated later on in a series of articles by Zegarlinski and Stroock, who proved the stronger condition of an exponential entropic decay of the dynamics towards the limiting Gibbs measure, also known as logarithmic Sobolev inequality. In this talk, we will prove an extension of the result of Zegarlinski and Stroock to the quantum setting. More precisely, we will show that, given the Gibbs state $\sigma$ of a 2-local commuting Hamiltonian and above a critical temperature, there exists a local quantum Markovian evolution converging to $\sigma$ which satisfies the quantum modified logarithmic Sobolev inequality (MLSI) with a constant that does not depend on the size of the lattice. As a first step towards this proof, we will also provide a proof of the existence of the MLSI for finite dimensional systems coupled to an arbitrarily large, noiseless environment (also known as the complete MLSI constant), a problem that was left open until now. This talk is based on the following papers: https://arxiv.org/abs/2009.11817 https://arxiv.org/abs/2102.04146 -------- Dottorato Matematica is inviting you to a scheduled Zoom meeting.

Fwd: [owps] One World Probability Seminar Thursday April 15, 2021
by Faggionato, Alessandra 14 Apr '21

14 Apr '21

Buongiorno vi inoltro l'annuncio del OWPS di domani (i moderatori sono cambiati). Saluti Alessandra ---------- Forwarded message --------- Da: Nina Gantert <nina.gantert(a)tum.de> Date: mer 14 apr 2021 alle ore 15:48 Subject: [owps] One World Probability Seminar Thursday April 15, 2021 To: <owps(a)lists.bath.ac.uk> Dear All, Tomorrow's speakers in the One World Probability Seminar are Peter Mörters and Markus Heydenreich. (Note: all times are in UTC. Due to time changes, you should check what that translates to in your location) ------------------------------------------------ (14:00-15:00 UTC) Speaker: Peter Mörters Percolation phase transition in random connection models I: Subcritical phase in weight-dependent models We investigate spatial random graphs defined on the points of a Poisson process in d-dimensional space, which combine scale-free degree distributions and long-range effects. Every Poisson point is assigned an independent weight. Given the weight and position of the points, we form an edge between any pair of points independently with a probability depending on the two weights of the points and their distance. Preference is given to short edges and connections to vertices with large weights. We characterize the parameter regime where there is a nontrivial percolation phase transition and show that it depends not only on the power-law exponent of the degree distribution but also on a geometric model parameter. Based on joint work with Peter Gracar and Lukas Luechtrath. (15:00-16:00 UTC) Speaker: Markus Heydenreich Percolation phase transition in random connection models II: Critical behaviour for weight-independent models We study the random connection model (without weights) in a regime where a percolation phase transition occurs: for low edge density there are finite connected components only, while for large density there is an infinite component a.s. Our interest is on the transition between the low- and high-density regime. We prove an infrared bound for the critical connection function if the dimension is sufficiently large or if the pair connectivity has sufficiently slow decay; this allows a detailed description of this transition. To this end, we devise the lace expansion for Poisson processes. Based on joint work with Remco van der Hofstad, Günter Last, and Kilian Matzke.

LTI@Unito/CCA webinar in QuantitativeFinance: “What matters in a characteristic?”, Hugues Langlois (HEC Paris) | April 20, 2021 @12:00
by Luca Regis 14 Apr '21

14 Apr '21

Dear Colleagues, I am happy to share with you the following invitation to the Quantative Finance webinar organized by LTI@UniTO and Collegio Carlo Alberto, “What matters in a characteristic?” by Hugues Langlois (HEC Paris), which will take place on Zoom on April 20, at 12.00. Below you find the Zoom link and an abstract of the presentation. Best regards, Luca Regis <#> <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/KjYRmqlKjrwhqhAdI2gLilGDSZjf_N3e7h…> <#> LTI@Unito and Fondazione Collegio Carlo Alberto are pleased to invite you to the next webinar <#> *April 20, 2021 | 12:00 - 13:15* *“What matters in a characteristic?”* * Hugues Langlois (HEC Paris)* <#> *Abstract*. We decompose firm characteristics into country, industry, and adjusted components and investigate their respective role in explaining expected returns and comovements in individual international stock returns. Models with adjusted components describe expected returns and comovements of individual stock returns better than models with unadjusted characteristics. While exposures to systematic risk factors are primarily explained by country components, alphas are predominantly driven by adjusted components. In contrast to the U.S. stock market, alphas in emerging and other developed markets are larger and significant. These rich empirical patterns inform models of stocks’ expected returns and comovements. *Zoom link* https://us02web.zoom.us/j/88521626111?pwd=cEdjUmdINERxZ3VzKzZuaXN5ZjEyZz09 <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/K-LOg1rFfgAp1Vis_nPzZABCDin-nMwdWK…> Meeting ID: 885 2162 6111 Passcode: 044353 <#> <#> <#> <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/G3qixTm9-N1P6dg7PFv3AK8C7TVOCc-7Yp…> <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/jtHbMvSIZkL41agMTsAl7rz6CCttgjbC7h…> <#> FONDAZIONE COLLEGIO CARLO ALBERTO Piazza Arbarello 8 - 10122 Torino, Italy phone: +390116705000 segreteria(a)carloalberto.org - www.carloalberto.org Facebook <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/zsLCc65Y9FomNLxNOcBSZGMOP7owve5tNm…> Twitter <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/5YX2pmxa-oc0WA3-iUV5-ciorC7wUYUyd2…> LinkedIn <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/WiJwT1Nk93TEFOV9ZwOihDt72sZCKlKyql…> Instagram <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/NaZEbS89ljbfvlcZWai2J42HH6phhDKVe8…> Youtube <https://4z5y5.r.a.d.sendibm1.com/mk/cl/f/ooK-g3SzwKowF2BfH3OuFQOAb1i_2ZONOT…> <#> *INFORMATION UNDER THE NEW GENERAL DATA PROTECTION REGULATION (GDPR)* Your personal information has been gathered for the exclusive purpose of informing you about the Collegio's initiatives, considering our and your legitimate interest or your consent.

Reminder: online seminar - Angelo Lucia (Caltech)
by Carbone Raffaella 13 Apr '21

13 Apr '21

Dear colleagues, it is our pleasure to invite you to the following seminar Speaker: *Angelo Lucia *(Caltech - Division of Physics, Mathematics and Astronomy) Title: *Mixing time of quantum Gibbs samplers* Time: Wednesday, *April 14*, 5PM (Italian time) The abstract follows below in this message. Zoom Link for the seminar <https://us02web.zoom.us/j/86771523774?pwd=SitEVEhPSGRlaEkxTHZmQk9rTmlLZz09> The seminar is a satellite activity of the PhD course "Introduction to coercive inequalities with applications in analysis and probability theory" (professor Boguslaw Zegarlinski - Imperial College, London) Best regards, Raffaella Carbone Abstract. Gibbs samplers are Markovian semigroups whose evolution converges towards the termal equilibrium of a given Hamiltonian (the Gibbs state). The time that the evolution takes, in the worst case, to converge close to the thermal state is known as the mixing time. Knowing the mixing time of a process is useful for many applications, and it can be estimated with various functional inequalities. In the case of classical spin systems on a lattice, it was shown that it is possible to determine the mixing properties of the semigroup from some "static" clustering condition of the thermal state. This suggests the question of whether the same is true for quantum spin systems. In this talk, I will focus on the specific case of Gibbs states of commuting Hamiltonians, and present some recent result in this direction. I will introduce the notion of quantum conditional relative entropy and show how it can be used to prove quasi-factorization (or approximate tensorization) properties of the quantum relative entropy. I will then show how these can be used to bound log-Sobolev constants for product semigroups with heath-bath generators, and under stronger assumptions in more general situations. -- Raffaella Carbone, PhD Probabilità e Statistica Matematica Dipartimento di Matematica dell'Università degli Studi di Pavia

Online Seminar by Cagin Ararat, Bilkent University (Wednesday, April 21, 15:30)
by Elisa Mastrogiacomo 09 Apr '21

09 Apr '21

*** Apologize for cross-posting *** On April Thursday 21 at 15:30, Cagin Ararat (Bilkent University) will give a virtual seminar “in Insubria & Bicocca”, to which you are all invited. Title and abstract below. Title: Set-valued martingales and backward stochastic differential equations Abstract: Motivated by the connection between univariate dynamic risk measures and backward stochastic differential equations, we start building a theory for set-valued backward stochastic differential equations (SV-BSDE). As a first step for this purpose, we formulate a simple SV-BSDE with a compact-valued driver function and study the well-posedness of this SV-BSDE. A key tool in establishing well-posedness is the availability of a stochastic integral representation for set-valued martingales. We prove a new martingale representation theorem which, in contrast to the available literature, allows the initial value of the martingale to be nontrivial. This is a joint work with Jin Ma (USC) and Wenqian Wu (USC). The seminar will be on Microsoft Teams. You can find the information to join below. Topic: Cagin Ararat - Set-valued martingales and backward stochastic differential equations Time: Apr 21, 2021 03:30 PM Rome Where: Microsoft Teams Link: https://teams.microsoft.com/l/meetup-join/19%3ameeting_Yzc1OGY5YjAtNjNhZC00… Please forward to anyone interested.

Seminario: Step-by-step community detection in volume-regular graphs, 9 Aprile ore 15
by Pietro Caputo 08 Apr '21

08 Apr '21

Seminario di Emilio Cruciani a Roma Tre: Emilio Cruciani (Universitaet Salzburg) Titolo: Step-by-step community detection in volume-regular graphs Venerdi' 09 Aprile 2021 ORE 15:00 Dipartimento di Matematica e Fisica Universita' degli Studi Roma Tre Abstract Spectral techniques have proved amongst the most effective approaches to graph clustering. However, in general they require explicit computation of the main eigenvectors of a suitable matrix (usually the Laplacian matrix of the graph). Recent work (e.g., Becchetti et al., SODA 2017) suggests that observing the temporal evolution of the power method applied to an initial random vector may, at least in some cases, provide enough information on the space spanned by the first two eigenvectors, so as to allow recovery of a hidden partition without explicit eigenvector computations. While the results of Becchetti et al. apply to perfectly balanced partitions and/or graphs that exhibit very strong forms of regularity, we extend their approach to graphs containing a hidden k-partition and characterized by a milder form of volume-regularity. We show that the class of k-volume regular graphs is the largest class of undirected (possibly weighted) graphs whose transition matrix admits k “stepwise” eigenvectors (i.e., vectors that have constant entries over the components corresponding to the same set of the hidden partition). To obtain this result, we highlight a connection between volume regularity and lumpability of Markov chains. Moreover, we prove that if the stepwise eigenvectors are those associated to the first k largest eigenvalues of the transition matrix of a random walk on the graph and the gap between the k-th and the (k+1)-th eigenvalues is sufficiently large, the Averaging dynamics of Becchetti et al. recovers the underlying community structure of the graph in logarithmic time, with high probability. Based on a joint work with Luca Becchetti, Francesco Pasquale, and Sara Rizzo.

07 Apr '21

Dear Colleagues, We would like to invite you to the following Probability seminar that will take place on April 16 at 12.00 by the zoom platform. ________________________________________________________ Speaker: Chiara Franceschini (IST Lisbona) Title: The symmetric inclusion process: some properties and scaling limit 16 APRIL (Friday) - 12:00 zoom link: TBA available on the webpage https://www.math.unipd.it/~bianchi/seminari/ ) Abstract: The symmetric inclusion process (SIP) is an interacting particle system discovered as the dual process of a Markov diffusion that conserves the total energy, it can be tough as the inclusion counterpart of the well-known exclusion process. In this talk, I will present the model with an open boundary, i.e. with two reservoirs which create a flux of particles in the bulk putting the model in a non-equilibrium setting. We will see that via the duality property, we can characterize some correlations of its stationary measure in non-equilibrium and we will also see what are, in this open setting, the so-called hydrodynamic and hydrostatic limit. -- Alessandra Bianchi Dip. di Matematica Università di Padova Via Trieste, 63 - 35121 Padova, Italy phone: +39 049 827 14 06 fax: +39 049 827 14 28 e-mail: bianchi(a)math.unipd.it http://www.math.unipd.it/~bianchi/

Dear colleagues, On April Thursday 22 at 14:30, prof. Clara Stegehuis (Twente University) will give a virtual seminar “in Florence”, to which you are all invited. You can find title and abstract below. Title: Optimal constrained and unconstrained subgraph structures Abstract: Subgraphs contain important information about network structures and their functions. We investigate the presence of subgraphs in a random graph model with infinite-variance degrees. We introduce an optimization problem which identifies the dominant structure of any given subgraph. The unique optimizer describes the degrees of the vertices that together span the most likely subgraph and allows us to count and characterize the asymptotic number of subgraphs in a simple manner. We then show that this optimization problem easily extends to investigating other random network structures, such as clustering, which expresses the probability that two neighbors of a vertex are connected. The optimization problem is able to find the behavior of network subgraphs in a wide class of random graph models. The seminar will be on Zoom. You can find the information to join below.

online seminar - Angelo Lucia - Mixing time of quantum Gibbs samplers
by Carbone Raffaella 07 Apr '21

07 Apr '21

Dear colleagues, it is our pleasure to invite you to the following seminar Speaker: *Angelo Lucia* Title: *Mixing time of quantum Gibbs samplers* Time: Wednesday, *April 14*, 5PM (Italian time) The abstract follows below in this message. Zoom Link for the seminar <https://us02web.zoom.us/j/86771523774?pwd=SitEVEhPSGRlaEkxTHZmQk9rTmlLZz09> The seminar is a satellite activity of the PhD course "Introduction to coercive inequalities with applications in analysis and probability theory" (professor Boguslaw Zegarlinski - Imperial College, London) Best regards, Raffaella Carbone Abstract. Gibbs samplers are Markovian semigroups whose evolution converges towards the termal equilibrium of a given Hamiltonian (the Gibbs state). The time that the evolution takes, in the worst case, to converge close to the thermal state is known as the mixing time. Knowing the mixing time of a process is useful for many applications, and it can be estimated with various functional inequalities. In the case of classical spin systems on a lattice, it was shown that it is possible to determine the mixing properties of the semigroup from some "static" clustering condition of the thermal state. This suggests the question of whether the same is true for quantum spin systems. In this talk, I will focus on the specific case of Gibbs states of commuting Hamiltonians, and present some recent result in this direction. I will introduce the notion of quantum conditional relative entropy and show how it can be used to prove quasi-factorization (or approximate tensorization) properties of the quantum relative entropy. I will then show how these can be used to bound log-Sobolev constants for product semigroups with heath-bath generators, and under stronger assumptions in more general situations. -- Raffaella Carbone, PhD Probabilità e Statistica Matematica Dipartimento di Matematica dell'Università degli Studi di Pavia

Pisa Online Seminars - Laure Dumaz and Martin Vogel (Tuesday, April 13 at 16:00 and 17:00)
by Giacomo Filippo Di Gesu 06 Apr '21

06 Apr '21

Dear colleagues, I would like to invite you to the following online seminar organized by the Probability group of the University of Pisa. The two talks will be accessible under the link Click here to join the meeting<https://teams.microsoft.com/l/meetup-join/19%3Aaf3d635091e049579e555a84219a…> Best regards, Giacomo Tuesday, April 13, 16:00 Speaker: Laure Dumaz (École Normale supérieure) Title: Localization of the continuous Anderson hamiltonian in 1-d and its transition towards delocalization. Abstract: We consider the continuous Schrödinger operator - d^2/d^x^2 + B’(x) on the interval [0,L] where the potential B’ is a white noise. We study the entire spectrum of this operator in the large L limit. We prove the joint convergence of the eigenvalues and of the eigenvectors and describe the limiting shape of the eigenvectors for all energies. When the energy is much smaller than L, we find that we are in the localized phase and the eigenvalues are distributed as a Poisson point process. The transition towards delocalization holds for large eigenvalues of order L. In this regime, we show the convergence at the level of operators. The limiting operator in the delocalized phase is acting on R^2-valued functions and is of the form ``J \partial_t + 2*2 noise matrix'' (where J is the matrix ((0, -1)(1, 0))), a form appearing as a conjecture by Edelman Sutton (2006) for limiting random matrices. Joint works with Cyril Labbé. Tuesday, April 13, 17:00 Speaker: Martin Vogel (Université de Strasbourg) Title: Eigenvalue asymptotics and eigenvector localization for non-Hermitian noisy Toeplitz matrices Abstract: A most notable characteristic of non-Hermitian matrices is that their spectra can be intrinsically sensitive to tiny perturbation. Although this spectral instability causes the numerical analysis of their spectra to be extremely unreliable, it has recently been shown to be also the source of new mathematical phenomena. I will present recent results about the eigenvalues asymptotics and eigenvector localization for deterministic non-Hermitian Toeplitz matrices with small additive random perturbations. These results are related to recent developments in the theory of partial differential equations. The talk is based on joint work with J. Sjöstrand, and with A. Basak and O. Zeitouni. ************************ Giacomo Di Gesù Dipartimento di Matematica Università di Pisa Largo Bruno Pontecorvo 5 56127 - Pisa, Italy giacomo.digesu(a)unipi.it<mailto:giacomo.digesu@unipi.it> https://sites.google.com/site/giacomodigesu/

Cari Colleghi lunedì prossimo 12 Aprile dalle 16 alle 18 avrà luogo il prossimo incontro per il ciclo di seminari Prisma. Gli speaker saranno Marco Fuhrman e Andrea Cosso, qui sotto titoli, abstract ed il link al collegamento Teams. ---------------------------------------------------------------- Speaker: Marco Fuhrman (Università di Milano) Title: A new tool in stochastic optimal control: the randomization method. Abstract: In the first part of this talk I will present a survery on the relationships among classical stochastic optimal control problems, non-linear partial differential equations (the Hamilton-Jacobi-Bellman equations) and backward stochastic differential equations (BSDEs). In the second part, more specifically, I will introduce the so-called randomization method, which allows to associate an appropriate BSDE to a large class of optimal control problems. Among the possible generalizations, I will concentrate on optimal control of path-dependent equations, i.e. equations with general with memory effects. Speaker: Andrea Cosso (Università di Bologna) Title: Randomization method and path-dependent Hamilton-Jacobi-Bellman equation Abstract: In the present talk I will study a stochastic optimal control problem with path-dependent coefficients. I will exploit the so-called randomization method to derive a dynamic programming principle for the value function. This allows to prove that the value function is a viscosity solution to a path-dependent Hamilton-Jacobi-Bellman equation, involving the horizontal and vertical derivatives of functional Ito calculus. Finally, I will discuss the validity of the comparison principle for such a partial differential equation.

WEBINARS IN STATISTICS @ COLLEGIO CARLO ALBERTO <https://www.carloalberto.org/events/category/seminars/seminars-in-statistic…> Venerdi 9 Aprile 2021, alle ore 12.00, si terrà il seguente webinar: ------------------------------------------------ Speaker: *Gilles Stupfler *(ENSAI Rennes and CREST, France) Title: *Asymmetric least squares techniques for extreme risk estimation* Zoom link: https://us02web.zoom.us/j/81720792366?pwd=QWtaYVRRejVSVGlOMXFMaDdsemxjdz09 Meeting ID: 817 2079 2366 Passcode: 241135 Abstract: Financial and actuarial risk assessment is typically based on the computation of a single quantile (or Value-at-Risk). One drawback of quantiles is that they only take into account the frequency of an extreme event, and in particular do not give an idea of what the typical magnitude of such an event would be. Another issue is that they do not induce a coherent risk measure, which is a serious concern in actuarial and financial applications. In this talk, I will explain how, starting from the formulation of a quantile as the solution of an optimisation problem, one may come up with two alternative families of risk measures, called expectiles and extremiles. I will give a broad overview of their properties, as well as of their estimation at extreme levels in heavy-tailed models, and explain why they constitute sensible alternatives for risk assessment using some real data applications. This is based on joint work with Abdelaati Daouia, Irène Gijbels, Stéphane Girard and Antoine Usseglio-Carleve. ------------------------------------------------ Il webinar è organizzato dalla "de Castro" Statistics Initiative www.carloalberto.org/stats Cordiali saluti, Pierpaolo De Blasi --- University of Torino & Collegio Carlo Alberto carloalberto.org/pdeblasi <https://sites.google.com/a/carloalberto.org/pdeblasi/>

Kind regards, Gianmarco Title: Reciprocity in a Preferential Attachment Network Abstract: Empirical studies show that online social networks have not only in- and out-degree distributions with Pareto-like tails, but also a high proportion of reciprocal edges. A classical directed preferential attachment (PA) model generates in- and out-degree distribution with power-law tails, but theoretical properties of the reciprocity feature in this model have not yet been studied. We derive the asymptotic results on the number of reciprocal edges between two fixed nodes, as well as the proportion of reciprocal edges in the entire PA network. We see that with certain choices of parameters, the proportion of reciprocal edges in a directed PA network is close to 0, which differs from the empirical observation. This points out one potential problem of fitting a classical PA model to a given network dataset with high reciprocity, and indicates alternative models need to be considered. ---------------------------------------------------------------------- Gianmarco Bet (he/him) Junior researcher https://gianmarco.bet Phone: (+39) 055 2751491 Department of Mathematics and Informatics "U.

Buongiorno, vi inoltro l'annuncio del OWPS di domani, che riguarderà il modello $\phi^4_3$. Quello di domani sarà l'ultimo OWPS prima della pausa di Pasqua. Il OWPS riprenderà dopo le vacanze (credo il 15 Aprile) con moderatori Nina Gantert and Julien Berestycki. Saluti Alessandra ---------- Forwarded message --------- Da: One World Probability <ow.probability(a)gmail.com> Date: mer 24 mar 2021 alle ore 09:09 Subject: [owps] One World Probability Seminar Thursday March 25, 2021 To: <owps(a)lists.bath.ac.uk> Tomorrow's speakers in the One World Probability Seminar are3(Note: all times are in UTC. *Due to time changes, you should check what that translates to in your location*) ------------------------------------------------ (14:00-15:00 UTC) Speaker: Hendrik Weber (University of Bath) Title: Phase transitions for $\phi^4_3$ - Part 1 Abstract: The $\phi^4$ model is a classical model in Mathematical Physics, arising e.g. as a continuous version of the Ising model, as a toy model for a Quantum field theory and it is also closely related to the invariant measures of certain Hamiltonian PDEs. The aim of this series of two talks is to discuss the infinite volume limit and the emergence of phase transitions for this model: we will show that in a certain parameter regime, the model exhibits a phase segregation behaviour, akin to the low temperature phase of the Ising model. In the first lecture I will put our result into perspective by first discussing the connection of continuous $\phi^4$ and discrete Ising models as well as the phase segregation in low temperature Ising models. I will then discuss a variational approach to estimating the $\phi^4$ partition function, which is due to Barashkov and Gubinelli and a key ingredient of our method. Based on Chandra, Gunaratnam, Weber, arXiv:2006.15933. (15:00-16:00 UTC) Speaker: Trish Gunaratnam (University of Geneva) Title: Phase transitions for $\phi^4_3$ - Part 2 Abstract: In this talk I will continue to discuss phase transitions for $\phi^4_3$. I will establish a surface order large deviations estimate for the average magnetisation at sufficiently low temperatures in large but finite volumes. This immediately gives an upper bound on the decay of the spectral gap for the associated $\phi^4_3$ singular SPDE in the infinite volume limit. At the heart of this result are the development of Peierls’ contour bounds for $phi^4_3$, which requires control over the small-scale divergences and the low temperature Hamiltonian. We achieve this by incorporating a low temperature expansion, inspired by Glimm, Jaffe, and Spencer’s classical work on $\phi^4_2$, within the variational representation of the $\phi^4_3$ via coarse-graining.

Sussex probability seminar
by Enrico Scalas 23 Mar '21

23 Mar '21

Dear Colleagues, Next Monday 29th March at 11am, we’ll have an online probability seminar with a talk given by Nicholas Simm. Title: The characteristic polynomial of a random unitary matrix: from secular coefficients to holomorphic multiplicative chaos Description: I will begin by introducing some basic questions / historical tidbits regarding eigenvalue statistics of random matrices. Then I will discuss some recent work concerning limit theorems for secular coefficients of random unitary matrices, which are the Fourier coefficients of the characteristic polynomial. This draws on ideas from Gaussian multiplicative chaos on the one hand, but also combinatorial structures such as magic squares and random permutations make an appearance. This is joint work with Joseph Najnudel (Bristol) and Elliot Paquette (McGill) , pre-print: https://arxiv.org/pdf/2011.01823.pdf. If you are interested in attending, please write to Dr Minmin Wang ( minmin.wang(a)sussex.ac.uk) for the Zoom link. Best wishes, Enrico Scalas

International Conference in Venice on COMPOUND RISK - CALL FOR PAPERS
by Monica Billio 21 Mar '21

21 Mar '21

20th INTERNATIONAL CONFERENCE CREDIT 2021 *Compound Risk: Climate, Disaster, Finance, Pandemic * Venice, Italy 23 –24 September 2021 * * *GRETA Associati* (Venice, Italy), *European Datawarehouse *(Frankfurt, Germany), *European Investment Bank* (Luxembourg), *European Investment Fund *(Luxembourg) and *Intesa Sanpaolo *(Milan, Italy) are co-sponsors of a Conference to be held in Venice on September 23-24, 2021. The Conference CREDIT 2021 will bring together academics, practitioners and PhD students working in various areas of financial and credit risk with the aim to create a unique opportunity for participants to discuss research progress and policy and industry-relevant insights as well as directions for future research. Credit 2021 is the *twentieth *in a series of events dedicated to various aspects of credit risk and organised under the auspices of the *Department of Economics* and *VERA - Venice centre in Economic and Risk Analytics for public policies - of the Ca’ Foscari University of Venice*, *ABI - Italian Banking Association*,***AIAF - Associazione Italiana per l'Analisi Finanziaria* and the *Joint Research Center, European Commission* (Ispra, Italy). The theme of this year’s conference is the relation between financial risk on the one hand and pandemic, climate and disaster risk, on the other hand, with particular attention to the possible compounding of different sources of risk. The past year, 2020, has been marked by the still-ongoing COVID-19 pandemic crisis, which has shown how fragile our economic systems can be when confronted with shocks that threaten public health and the closeness of the connections between economic and financial risks and public policy. Climate change is now widely recognized as a new source of financial risk which is relevant both at the level of households and individual institutions and the systemic level. In particular, the many central banks and financial institutions that have joined the Network for Greening the Financial System (NGFS) have issued recommendations on how to integrate climate considerations into risk management strategies and practices. However, risks such as pandemics and climate change do not occur in isolation but can also compound, as has already been seen in several countries. The compounding of risk, which is currently poorly understood, increases the complexity of risk assessment and risk management, and it has implications for socio-economic development, as well as for public debt sustainability. In the EU, these aspects have major implications for efforts to increase the resilience of the economy to future shocks and to “build back better”, and requires the alignment of COVID-19 recovery policies, such as those supported by the NextGenerationEU, and the EU Green Deal and the Paris Agreement targets. The organizers of CREDIT 2021 encourage submissions on a range of topics of relevance to this year’s theme including: finance and COVID-19; finance and climate risks; finance and compound COVID-19 and climate risks. In particular, submissions are welcome in the following areas: • INVESTMENTS: Sustainable Finance, Disaster risk finance; Finance 4 good; public finance; blended finance. • POLICIES: Climate Policies, European Green New Deal; Next Generation EU; Recovery Plan. • INFORMATION: Data gaps; modelling challenges; risk transmission channels; uncertainty; complexity. The final program will include both submitted and invited papers. Acceptances received so far from invited speakers include *Vittoria Colizza *(INSERM, France), *Robert Engle *(Stern Business School, New York University) and *Roberto Rigobon* (MIT Sloan School of Management) who will deliver keynotes, respectively on finance and on epidemics. The Conference will also feature panel discussions on researchers', practitioners' and policy makers’ views of the major issues at stake. The SCIENTIFIC COMMITTEE for the Conference consists of: • * Stefano Battiston *(Ca’ Foscari University of Venice & University of Zurich, Programme Chair) • * Monica Billio *(Ca’ Foscari University of Venice & GRETA) • * Francesca Campolongo *(Joint Research Center, European Commission) • *Vittoria Colizza* (INSERM, France) • * Helmut Kraemer-Eis* (European Investment Fund) • * Jan Pieter Krahnen* (Leibniz Institute for Financial Research SAFE & Goethe University, Frankfurt) • *Irene Monasterolo *(Vienna University of Economics and Business) • *Steven Ongena* (University of Zurich, Swiss Finance Institute, KU Leuven & CEPR) • *Roberto Rigobon* (MIT Sloan School of Management) • *Stephen Schaefer* (London Business School) CALL FOR PAPERS Those wishing to present a paper at the Conference should submit by *May 31, 2021 *to the address given below (preferably in electronic format). Please indicate to whom correspondence should be addressed. Decisions regarding acceptance will be made by *June 30, 2021*. The final version of accepted papers must be received by August 31, 2021.

LTI@Unito Webinars: March 1, Massimiliano Caporin | March 2, Roberto Renò
by Luca Regis 18 Mar '21

18 Mar '21

Dear colleagues, || |LTI@UniTO (www.carloalberto.org/lti <www.carloalberto.org/lti>) and Fondazione Collegio Carlo Alberto are pleased to invite you to the following webinars in Mathematical Finance: | | *March 1, 2021 | 17:00-18:00* *“Do jumps matter in Realized Volatility modeling and forecasting? Empirical evidence and a new model”* *Massimiliano Caporin, University of Padova* *Abstract*: Building on an extensive empirical analysis I investigate the relevance of jumps and signed variations in predicting Realized Volatility. I show that properly accounting for intra-day volatility patterns and staleness sensibly reduces the identified jumps. Realized Variance decompositions based on intra-day return size and sign improve the in-sample fit of the models commonly adopted in empirical studies. I also introduce a novel specification based on a more informative decomposition of Realized Volatility, which offers improvements over standard models. From a forecasting perspective, the empirical evidence I report shows that most models, irrespective of their flexibility, are statistically equivalent in many cases. This result is confirmed with different samples, liquidity levels, forecast horizons and possible transformations of the dependent and explanatory variables. *Zoom Link: https://us02web.zoom.us/j/82672618584?pwd=VWdNeWhEc1pyVjJCQ3pucEhtb1BxUT09 <https://us02web.zoom.us/j/82672618584?pwd=VWdNeWhEc1pyVjJCQ3pucEhtb1BxUT09>* Meeting ID: 826 7261 8584 Passcode: 599584 ------ *March 2, 2021 | 12:00-13:15 * *“V-shapes”* *Roberto Renò, University of Verona* *Abstract*: An insidious form of market inefficiency, by which prices lose their informativeness and wealth is distributed arbitrarily, translates into V-shapes, that is sudden changes of the sign of the price drift. We use this insight to develop a new tool for the detection of reverting drift, the V-statistic. We apply this tool to (i) quantify the extent of this kind of market inefficiency in the U.S. stock market during the Covid-19 pandemic; and (ii) show the harmful consequences of V-shapes on financial stability by estimating the huge loss suffered by Italian taxpayers (0.45B euros) in May 2018, when a transient crash hit the secondary bond market during a Treasury auction. /Joint with Maria Flora./ *Zoom link https://us02web.zoom.us/j/82590058916?pwd=VEowc2NUcm5rNmtFdWQ0MlMxUEVLQT09 <https://us02web.zoom.us/j/82590058916?pwd=VEowc2NUcm5rNmtFdWQ0MlMxUEVLQT09>* Meeting ID: 825 9005 8916 Passcode: 055411 We look forward to your participation! | -- Luca Regis Associate Professor Department of Economics and Statistics (ESOMAS) University of Torino sites.google.com/view/lucaregis Office: +39 011 670 6065 www.carloalberto.org/lti ||

Padova Online Seminar by Luisa Andreis (Università di Firenze) [Friday, Mar. 26 at 14.30]
by alessandra bianchi 18 Mar '21

18 Mar '21

Dear Colleagues, We would like to invite you to the following Probability seminar that will take place on March 26 at 14.30 by the zoom platform. ________________________________________________________ Speaker: Luisa Andreis (Università di Firenze) Title: Phase transitions in sparse random graphs and coagulation processes 26 MARCH (Friday) - 14:30 zoom link: TBA available on the webpage https://www.math.unipd.it/~bianchi/seminari/ ) Abstract: Sparse inhomogeneous random graphs are a natural generalization of the well-known Erdos Rényi random graph, where vertices are characterized by a type and edges are independent but distributed according to the type of the vertices that they are connecting. These graphs undergo a phase transition in terms of the emergence of a giant component exactly as the classical Erdos Rényi model. In this talk we will present an alternative approach, via large deviations, to prove this phase transition. This allows a comparison with the gelation phase transition that characterizes coagulation processes and the phase transition of condensation type emerging in several systems of interacting components. This is an ongoing joint work with Wolfgang Koenig (WIAS and TU Berlin), Robert Patterson (WIAS) and Heide Langhammer (TU Berlin). -- Alessandra Bianchi Dip. di Matematica Università di Padova Via Trieste, 63 - 35121 Padova, Italy phone: +39 049 827 14 06 fax: +39 049 827 14 28 e-mail: bianchi(a)math.unipd.it http://www.math.unipd.it/~bianchi/

Buongiorno inoltro l'annuncio del OWPS di domani, che sarà focalizzato sul metodo di Stein (anche con applicazioni alla statistica). Saluti Alessandra ---------- Forwarded message --------- Da: One World Probability <ow.probability(a)gmail.com> Date: mer 17 mar 2021 alle ore 12:06 Subject: [owps] One World Probability Seminar Thursday March 18, 2021 To: <owps(a)lists.bath.ac.uk> Tomorrow's speakers in the One World Probability Seminar are (Note: all times are in UTC. *Due to time changes, you should check what that translates to in your location*) ------------------------------------------------ (14:00-15:00 UTC) Speaker: Yvik Swan (Université Libre de Bruxelles) Title: Stein’s density approach Abstract: Stein’s method is a collection of tools allowing to obtain explicit (non-asymptotic) bounds on discrepancies between probability distributions. The heart of the method is a so-called “Stein operator”, and it is the objective of this talk to present the basic theory behind these operators, and also cover some applications of the theory. After presenting the general theory (with a focus on Stein’s so-called density approach), we will give details on the 1-dimensional case, hereby connecting with classical topics such as Covariance and Poincaré inequalities. The material covered in the talk is closely related to work with Marie Ernst, Christophe Ley, Guillaume Mijoule and Gesine Reinert. (15:00-16:00 UTC) Speaker: Gesine Reinert (University of Oxford) Title: Stein’s method for multivariate continuous distributions and some statistical applications Abstract: Stein’s method can be viewed as employing an operator which action characterises a distribution uniquely, relating this operator to test functions through a Stein equation, and comparing distributions by taking expectations of this Stein equation. Using the density approach for Stein’s method, this talk will present a general framework for Stein’s method for multivariate continuous distributions. For any given nontrivial distribution this approach leads to an infinite collection of Stein characterisations which can be used to assess distributional distances. We shall apply this framework to compare posterior distributions which arise from the same model but using different priors. Using the notion of a weak Stein equation, bounds on distributional distances based on Lipschitz test functions are obtained if the distribution admits a Poincare’ constant. This result will be used to compare copulas. Finally, using the notion of a Stein kernel, we shall extend Stein’s shrinkage results and Stein’s Unbiased Risk Estimate (SURE) to non-Gaussian distributions. This talk is based on joint work with Max Fathi, Larry Goldstein, Adrien Saumard, and of course Yvik Swan. ------------------------------------------------ The zoom link will appear the day before on the OWPS website: https://www.owprobability.org/one-world-probability-seminar <https://eur01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.owpro…> It can also be directly accessed through the link below: https://uniroma1.zoom.us/j/81951703647?pwd=QUR4M0QraDFTZG5qY0VvVmVoS0pnZz09 <https://eur01.safelinks.protection.outlook.com/?url=https%3A%2F%2Funiroma1.…> Meeting ID: 819 5170 3647 Passcode: 614352 Please feel free to circulate this email.

Pisa Online Seminars - Michela Ottobre and Andrea Agazzi (Tuesday, Mar. 23 at 16:00 and 17:00)
by Giacomo Filippo Di Gesu 16 Mar '21

16 Mar '21

Dear colleagues, I would like to invite you to the following online seminar organized by the Probability group of the University of Pisa. The two talks will be accessible under the link Click here to join the meeting<https://teams.microsoft.com/l/meetup-join/19%3A17115d7f6ef44c5e91974362906c…> Best regards, Giacomo Tuesday, March 23, 16:00 Speaker: Michela Ottobre (Heriot-Watt University Edinburgh) Title: Uniform in time approximations of stochastic dynamics Abstract: Complicated models, for which a detailed analysis is too far out of reach, are routinely approximated via a variety of procedures; this is the case when we use multiscale methods, when we take many particle limits and obtained a simplified, coarse-grained dynamics, or, simply, when we use numerical methods. While approximating, we make an error which is small over small time-intervals but it typically compounds over longer time-horizons. Hence, in general, the approximation error grows in time so that the results of our ``predictions" are less reliable when we look at longer time-hormizons. However this is not necessarily the case and one may be able to find dynamics and corresponding approximation procedures for which the error remains bounded, uniformly in time. We will discuss a very general approach to understand when this is possible. I will show how the approach we take is very broad and show how it can be used for all of the approximation procedures mentioned above. This is based on a series of joint works with a number of people: L. Angeli, J. Barre', D. Crisan, P. Dobson, I. Souttar and E. Zatorska. Tuesday, March 23, 17:00 Speaker: Andrea Agazzi (Duke University) Title: Large deviations for stochastic models of chemical reaction networks Abstract: At the microscopic level, the dynamics of arbitrary networks of chemical reactions can be modeled as jump Markov processes whose sample paths converge, in the limit of large number of molecules, to the solutions of a set of algebraic ordinary differential equations. Fluctuations around these asymptotic trajectories and the corresponding phase transitions can in principle be studied through large deviations theory in path space, also called Wentzell-Freidlin (W-F) theory. However, the specific form of the jump rates for this family of processes does not satisfy the standard regularity assumptions imposed by such theory. This talk discusses how such conditions can be relaxed. In this talk, I will discuss sufficient stability and nondegeneracy conditions on the given family of Markov jump processes to obtain the desired large deviations estimates, and show how some of these conditions can be translated into structural ones, facilitating their verification for large chemical networks. ************************ Giacomo Di Gesù Dipartimento di Matematica Università di Pisa Largo Bruno Pontecorvo 5 56127 - Pisa, Italy giacomo.digesu(a)unipi.it<mailto:giacomo.digesu@unipi.it> https://sites.google.com/site/giacomodigesu/

Seminar announcement Thursday 25 - Reciprocity in a Preferential Attachment Network (prof. Tiandong Wang)
by Gianmarco Bet 16 Mar '21

16 Mar '21

Dear colleagues, On March Thursday 25 at 16:00, prof. Tiandong Wang (Texas A&M) will give a virtual seminar “in Florence”, to which you are all invited. You can find title and abstract below. Title: Reciprocity in a Preferential Attachment Network Abstract: Empirical studies show that online social networks have not only in- and out-degree distributions with Pareto-like tails, but also a high proportion of reciprocal edges. A classical directed preferential attachment (PA) model generates in- and out-degree distribution with power-law tails, but theoretical properties of the reciprocity feature in this model have not yet been studied. We derive the asymptotic results on the number of reciprocal edges between two fixed nodes, as well as the proportion of reciprocal edges in the entire PA network. We see that with certain choices of parameters, the proportion of reciprocal edges in a directed PA network is close to 0, which differs from the empirical observation. This points out one potential problem of fitting a classical PA model to a given network dataset with high reciprocity, and indicates alternative models need to be considered. The seminar will be on Zoom. You can find the information to join below. Topic: Tiandong Wang - Reciprocity in a Preferential Attachment Network Time: Mar 25, 2021 04:00 PM Rome https://us02web.zoom.us/j/82762436142?pwd=MW45SWN6NTBqV0VWbVJWREhESmtaZz09 Meeting ID: 827 6243 6142 Passcode: 897951 If you know of someone who might be interested and is not subscribed to the random mailing list, please do not hesitate to forward this announcement to them.

WEBINARS IN STATISTICS @ COLLEGIO CARLO ALBERTO <https://www.carloalberto.org/events/category/seminars/seminars-in-statistic…> Venerdi 19 Marzo 2021, alle ore 17:00, si terrà il seguente webinar: ------------------------------------------------ Speaker: *Andrea Ottolini (*Standford University, USA) Title: *Gibbs sampling in the analysis of priors for almost exchangeable data* Zoom link: https://us02web.zoom.us/j/83130864007?pwd=Z2dGbHVsWHJMMG9iaTJFb2VMcExqQT09 Meeting ID: 831 3086 4007 Passcode: 222589 Abstract: Consider a population of N individuals divided into d subgroups (e.g., d=4 and people are divided by sex and smoking habits). A sequence of 0-1 valued experiments on the population with outcomes X_1,..., X_n is called partially exchangeable if the only relevant information in the data is the number of 1's in each category. de Finetti's representation result guarantees that the distribution of the X's (for n<<N) is in bijection with measures pi^{(n)} on [0,1]^d. Natural problems -- such as understanding which of the subdivisions are truly meaningful and what is the effect of our initial belief pi^{(0)} -- can be addressed if one knows how to sample efficiently from these measures. In the absence of further information about the experiments, de Finetti suggests starting with a class of priors pi^{(0)}_{C,A} indexed by a d-dimensional network (measuring the relative differences among categories) and a positive parameter A (measuring the belief in complete exchangeability). in this talk I will analyze the performance of Gibbs sampling in approximating these measures in the almost exchangeable regime (A>>1). It will be shown that A^2 steps are necessary and sufficient to mix in a certain Wasserstein distance, with constants depending on few spectral parameters of the network C. This is based on joint work with Gerencsér. ------------------------------------------------ Il webinar è organizzato dalla "de Castro" Statistics Initiative www.carloalberto.org/stats in collaborazione con il Collegio Carlo Alberto e rientra nel Complex Data Modeling Research Network midas.mat.uc.cl/network Cordiali saluti, Pierpaolo De Blasi --- University of Torino & Collegio Carlo Alberto carloalberto.org/pdeblasi <https://sites.google.com/a/carloalberto.org/pdeblasi/>

Fwd: [owps] One World Probability Seminar Thursday March 11, 2021

Buongiorno inoltro l'annuncio per il OWPS di domani, che sarà relazionato alla biologia. Saluti Alessandra ---------- Forwarded message --------- Da: One World Probability <ow.probability(a)gmail.com> Date: mer 10 mar 2021 alle ore 09:32 Subject: [owps] One World Probability Seminar Thursday March 11, 2021 To: <owps(a)lists.bath.ac.uk> Tomorrow's speakers in the One World Probability Seminar are (Note: all times are in UTC. *Due to time changes, you should check what that translates to in your location*) ------------------------------------------------ (14:00-15:00 UTC) Speaker: Viet Chi Tran (Université Gustave Eiffel) Title: Limit Theorems for Historical Particle Systems Abstract: To describe the evolving phylogenies of a birth and death process with trait structure and ecological interactions, we build a historical process inspired by works by Dawson and Perkins (1991 and 1995): it is a càdlàg process whose value at time t is a measure on lineages stopped at this time, i.e. paths describing the trait ancestries of the individuals living at time t. The dynamics may depend on past traits and allows interactions between individuals through their lineages. We establish the convergence of the individual-based birth-death process to a nonlinear historical superprocess, under the assumptions of large populations, small individuals and allometric demographies. The limit is described here by a macroscopic martingale problem. Because of the interactions, the branching property fails and we use fine couplings between our population and independent branching particles. This is a joint work with Sylvie Méléard. (15:00-16:00 UTC) Speaker: Sylvie Méléard (École Polytechnique, Paris) Title: Historical Processes and Dynamics of Phylogenies in a Population with Climate Change Abstract: We investigate in a simple model how the phylogenies of living individuals are shaped by the adaptation to a varying environment. In this model, the individuals are characterised by one-dimensional real traits (or positions). The stochastic individual-based birth-death process depends on a time-changing growth rate that shifts the optimal trait to the right and depends on a nonlinear logistic competition term. The macroscopic behaviour is described by a PDE that admits a unique positive stationary solution. We are interested here in the ancestral lineages of the living individuals in the stationary regime. The dynamic of these lineages is modelled by a historical process, approximatively close to a similar one with non-linearity frozen to its stationary value. We then use a many-to-one identity together with Feynman-Kac's formula and fine stochastic calculus to completely describe the limiting distribution, in large populations, of the path of an individual drawn at random at a given time. This path, in reversed time, is approximated by a simple Ornstein-Uhlenbeck. It shows how the lagged bulk of the present population stems from ancestors once optimal in trait but still in the tail of the trait distribution in which they lived. This talk is based on a joint work with Vincent Calvez, Benoit Henry and Viet Chi Tran. ------------------------------------------------ The zoom link will appear the day before on the OWPS website: https://www.owprobability.org/one-world-probability-seminar <https://eur01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.owpro…> It can also be directly accessed through the link below: https://uniroma1.zoom.us/j/86028841260?pwd=bUxyVUYzSjY5dDR4d3krb2lDTHZDQT09 <https://eur01.safelinks.protection.outlook.com/?url=https%3A%2F%2Funiroma1.…> Meeting-ID: 860 2884 1260 Passcode: 868252 Please feel free to circulate this email.

This year, we will be able to accept more applications than usual (about 10, compared to 7 usually). Bézout Master program is directed towards excellent students in mathematics or computer science (or both) from foreign institutions willing to pursue their studies in Université Paris-Est at the master's level. The laureates will receive about 1300 € per month over 11 months (pending approval of the University Executive Board) and will be proposed a room on the campus. Furthermore, the best students will then be invited to join the PhD program of the Doctoral School MSTIC (Mathematics, Sciences and Information and Communication Technology). A joint supervision with the student's national doctoral framework, leading to both PhD grades, is possible. The details of the program can be found here: http://bezout.univ-paris-est.fr/masters-scholarships/ <http://bezout.univ-paris-est.fr/masters-scholarships/> . From the same webpage, a link to the application form is available; the deadline will be May 21. On April 27 and 30, we plan to hold two online presentations of the Bézout master's program and scholarships, followed by a session of questions and answers; potential applicants should express their interest (without commitment to attend), so that we can send them the credentials for the meeting; see the webpage. A description of the activities of the Bézout Labex can be found in the leaflet at http://bezout.univ-paris-est.fr/wp-content/uploads/2020/11/bezout-leaflet.p….

Webinar Yi Yu @Bocconi
by Giacomo Zanella 09 Mar '21

09 Mar '21

We announce the following DEC Statistics webinar: Date: Thursday, March 11, h17:00 (Italy time) Speaker: Yi Yu (University of Warwick) Title: Functional Linear Regression with Mixed Predictors Abstract: We study a functional linear regression model that deals with functional responses and allows for both functional covariates and high-dimensional vector covariates. The proposed model is flexible and nests several functional regression models in the literature as special cases. Based on the theory of reproducing kernel Hilbert spaces (RKHS), we propose a penalized least squares estimator that can accommodate functional variables observed on discrete grids. Besides the conventional smoothness penalties, a group Lasso-type penalty is further imposed to induce sparsity in the high-dimensional vector predictors. We derive finite sample theoretical guarantees and show that the excess prediction risk of our estimator is minimax optimal. Furthermore, our analysis reveals an interesting phase transition phenomenon that the optimal excess risk is determined jointly by the smoothness and the sparsity of the functional regression coefficients. A novel efficient optimization algorithm based on iterative coordinate descent is devised to handle the smoothness and sparsity penalties simultaneously. Simulation studies and real data applications illustrate the promising performance of the proposed approach compared to the state-of-the-art methods in the literature. The webinar will be on zoom at: https://zoom.us/j/95651583993?pwd=ZnZjaGxvZWVLdGFSL0dGTk43eU9Idz09 Meeting ID: 956 5158 3993 Passcode: 568279 Kind regards, Giacomo Zanella
