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

Dear All, I am forwarding the announcement below, which may be of interest to young researchers in the applied probability community. Best wishes Tiziano *-------------------------3 POSTDOCTORAL FELLOWSHIPS IN MODELING AND ENGINEERING RISK AND COMPLEXITY (MERC) AVAILABLE AT THE SSM-SCHOOL FOR ADVANCED STUDIES OF THE UNIVERSITY OF NAPLES (Call no. MERC_021_01)* The call for applications for three postdoctoral fellowships in Modeling and Engineering Risk and Complexity iat the SSM-School for Advanced Studies of the University of Naples is now available at: http://www.ssm.unina.it/en/postdoctoral-fellowships-calls-and-procedures/ The research programme will focus on the development of new methodological approaches for the study, management and control of complex systems, the design and engineering of resilient systems and the analysis and management of risks (natural, anthropogenic, industrial and na-tech) and cascading effects. The programme focuses on the integrated description and management of phenomena affecting complex systems and the risks to which they are exposed, in different application domains, through the use of methods for mathematical, stochastic, computational and data-driven modelling. The programme should be characterised by a strongly multi- and inter-disciplinary approach, based on the theory of dynamical systems and control, the study of complex systems, infrastructures and networks, the theory of reliability for the modelling of uncertainty, the analysis and management of risks deriving from natural and anthropic phenomena on complex and interdependent systems and the study of their emerging properties and domino and cascade effects. The candidate's activity should lie in at least one of the following three multidisciplinary research areas (i) modelling, analysis and control of non-linear, uncertain, complex and multi-agent systems (ii) stochastic modelling and reliability theory (iii) Modelling and analysis of natural, Na-Tech, man-made and industrial hazards. The winners will carry out their research at the Scuola Superiore Meridionale of the Università degli Studi di Napoli Federico II in close collaboration with the research groups already involved in the activities of the PhD students active there. They will also be required to engage in the teaching and tutoring activities of the School, by either giving courses at PhD level or undergraduate level for the students of the School. Each fellowship is 1 year long (renewable up to 3 years) with a yearly gross salary of EUR 35,000. *Deadline for applications: 31st July 2021 at 2pm CET.* For any further information you can check the related PhD program website at http://www.ssm.unina.it/en/modeling-and-engineering-risk-eng-and-complexity… or contact us via email at merc(a)unina.it <https://mailto:merc@unina.it>

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.

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.

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.

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.

Care/i iscritte/i, il Dipartimento di Scienze di Base e Applicate per l'Ingegneria di "Sapienza Università di Roma" bandisce un *assegno di ricerca di categoria B - tipologia I* annuale (rinnovabile) dal titolo "*Analisi e sviluppo di modelli per l'interazione tra molecole di DNA e substrato nanostrutturato*" all'interno del Progetto DIANA - "DIAgnostic potential of disorder: development of an innovative NAnostructured platform for rapid, label-free and low-cost analysis of genomic DNA" (IT) Il progetto di ricerca riguarda lo sviluppo e l’applicazione di tecniche statistiche finalizzate allo studio di dati spettrali ottenuti dall’analisi per deposizione diretta della soluzione contenente le molecole target di DNA genomico su vetrini standard da microscopia appositamente ricoperti dalle nanostrutture sonda e letti da apparati Raman. 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. 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.
