Seminar announcement July Thursday 8 - Metastability for the dilute Curie-Weiss model with Glauber dynamics (prof. Elena Pulvirenti)
by Gianmarco Bet 07 Jul '21

07 Jul '21

Dear colleagues, On July Thursday 8 at 14:00, prof. Elena Pulvirenti (TU Delft) will give a virtual seminar “in Florence”, to which you are all invited. You can find title and abstract below. Title: Metastability for the dilute Curie-Weiss model with Glauber dynamics Abstract: We analyse the metastable behaviour of the dilute Curie–Weiss model subject to a Glauber dynamics. The model is a random version of a mean-field Ising model, where the coupling coefficients are replaced by i.i.d. random coefficients, e.g. Bernoulli random variables with fixed parameter p. This model can be also viewed as an Ising model on the Erdos–Renyi random graph with edge probability p. The system is a Markov chain where spins flip according to a Metropolis dynamics at inverse temperature \beta. We compute the average time the system takes to reach the stable phase when it starts from a certain probability distribution on the metastable state (called the last-exit biased distribution), in the regime where the system size goes to infinity, the inverse temperature is larger than 1 and the magnetic field is positive and small enough. We obtain asymptotic bounds on the probability of the event that the mean metastable hitting time is approximated by that of the Curie–Weiss model. The proof uses the potential theoretic approach to metastability and concentration of measure inequalities. This is a joint collaboration with Anton Bovier (Bonn) and Saeda Marello (Bonn). The seminar will be on Zoom. You can find the information to join below.

29 Jun '21

Dear Colleagues, We would like to invite you to the following Probability seminar that will take place on July 9 at 14.30 by the zoom platform. ________________________________________________________ Speaker: Wioletta Ruszel (University of Utrecht) Title: Local central limit theorem and potential kernel estimates for a class of symmetric heavy-tailed random variables. 09 JULY (Friday) - 14:30 zoom link: TBA available on the webpage https://www.math.unipd.it/~bianchi/seminari/ ) Abstract: In this talk we will discuss stable local limit theorems and potential kernel estimates. In particular we consider a class of heavy-tailed random variables on Z in the domain of attraction of an -stable random variable of index \alpha \in (0, 2) satisfying a certain expansion of their characteristic function expansion. Our results include sharp convergence rates for the local (stable) central limit theorem, a detailed expansion of the characteristic function of a long-range random walk with transition and detailed asymptotic estimates of the discrete potential kernel. This is joint work with Leandro Chiarini (UU) and Milton Jara (IMPA) and is based on arXiv.com/2101.01609. -- 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/

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.

Annuncio: GNU TeXmacs versione 2.1
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. With our best regards, The TeXmacs team

Dear colleagues, I am happy to forward you the following announcements of two seminars in Quantitative Finance organized by LTI@UniTO and Collegio Carlo Alberto: * Matthijs Breugem (CCA) on Tuesday, June 29th: "On the impact of Long Term Investors on Information Choice and Market Efficiency" * Carole Bernard (Grenoble Ecole de Management) on Thursday July 1st: "Option-implied dependence and correlation risk premium". 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.

23 Jun '21

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.

In particolare, al fine di analizzare i risultati sperimentali, saranno applicati diversi metodi statistici per ridurre ed interpretare i dati ottenuti, come ad esempio l’Analisi in Componenti Principali (ACP) o l’Analisi Fattoriale (AF). L’obiettivo sarà quello di individuare eventuali clusters di dati associati a possibili esiti nell’ambito della diagnostica del DNA in campo oncologico. Ulteriore finalità sarà quindi quella di sviluppare modelli predittivi, in grado di individuare l’appartenenza ad un determinato cluster di nuovi dati. Il lavoro di analisi statistica sarà sviluppato mediante uno o più linguaggi di programmazione (R Cran, Python, Matlab...). (EN) The research project regards the development and the application of statistical techniques aimed to study spectral data obtained by the analysis of spectral data from the direct deposition of the solution containing target molecules of genomic DNA on standard microscopy slides covered by the probe nanostructures and read by Raman machines. In particular, to analyze the experimental results, several different methods will be applied to the data, such as Principal Component Analysis (PCA) and Factorial Analysis (FA). The target is to identify potential clusters of data related to possible outcomes in the setting of DNA diagnostic in the oncology framework. Another goal is to develop predictive models, to identify the belonging of new data to a given cluster. The work of statistical analysis will be performed within one or more programming languages (R Cran, Python, Matlab...)

Buongiorno sotto l'annuncio del OWPS di domani. Grazie dell'attenzione Saluti Alessandra ---------- Forwarded message --------- Da: One World Probability <ow.probability(a)gmail.com> Date: mer 16 giu 2021 alle ore 08:05 Subject: [owps] To: <owps(a)lists.bath.ac.uk> Dear All, Thursday June 17 we have two talks, by Amir Dembo and Nick Cook. (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.

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.

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, “Investor Behavior under Prospect Theory: Evidence from Mutual Funds” by Lorenzo Schoenleber (CCA), which will take place on Zoom on June 14th, 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/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.

(PMS)^2 online talk: Vincent Martinez, Monday June 14 at 17.30
by Margherita Zanella 09 Jun '21

09 Jun '21

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.

Fwd: [owps] OWPS: two talks thursday June 3
by Faggionato, Alessandra 02 Jun '21

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
