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. The webinar will be on zoom at: https://zoom.us/j/97942632075?pwd=eDhNTlREdU5UVGpMcDVPSWV2bU5nQT09 Meeting ID: 979 4263 2075 Passcode: 627490 Kind regards, Giacomo Zanella [La tua firma può scrivere un futuro.

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/ @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
