They appear in statistical physics, random matrix theory, vortex systems, constructive approximation… and can be seen as a (possibly infinite) random collection of points that exhibit interesting stochastic features depending on the length scale and the temperature T. For example, their global arrangement is predicted by a mean field model and is found to be independent of T, whereas their local arrangement varies wildly with T while conserving strong, surprising rigidity properties all along. I will present some basic facts about the analysis of Coulomb gases and mention a few long-standing questions around which recent developments have taken place. (15:00-16:00 UTC) Sylvia Serfaty (NYU Courant) Title: Local laws and fluctuations for Coulomb gases Abstract: We are interested in the statistical mechanics of systems of N points with Coulomb interactions in general dimension for a broad temperature range. We discuss local laws characterizing the rigidity of the system at the microscopic level, as well as free energy expansion and Central Limit Theorems for fluctuations. ------------------------------------------------ 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/84008096626?pwd=N3MyYUFaMElvazIrS3hzNE1aSnRRZz09 <https://eur01.safelinks.protection.outlook.com/?url=https%3A%2F%2Funiroma1.…> Please feel free to circulate this email.

Talk by Arturo Jaramillo [Jan 19, 4:30pm - Zoom]
by Maurizia Rossi 13 Jan '21

13 Jan '21

Dear all, I would like to announce the following online seminar that will take place next week via the Zoom platform. Best regards, Maurizia Rossi *Tuesday, Jan 19 - 4:30pm *(Rome time zone) Speaker: *Arturo Jaramillo Gil* (*CIMAT -* Centro de Investigación en matemáticas, Mexico) Title: *Quantitative Erdös-Kac theorem for additive functions* Summary: The talk will take as a starting point the celebrated Erdös-Kac theorem; a result of great importance in probabilistic number theory, which establishes that the fluctuations of the number of prime factors in a uniform sample over {1,..., n} are asymptotically Gaussian. Naturally, after the publication of this result, many quantitative versions of it have been studied. LeVeque conjectured that the optimal rate was asymptotically equivalent to loglog(n)^(-1/2). This was later proved by Turan and Rényi by means of an ingenious manipulation of the underlying characteristic function. Unfortunately, up to this day, all the perspectives for solving LeVeque's conjecture are based on the use of non-trivial complex analysis tools, while the probabilistic perspective has been only successfully applied to obtain suboptimal rates of convergence. In this talk, we will give a purely probabilistic proof of LeVeque's conjecture which will allow us to address the problem in a general fashion by means of Stein's method techniques. *Link Zoom* https://us02web.zoom.us/j/88100676046?pwd=NTFjdlAyVjdSTE8rVnBmUGVWelFPdz09 *Meeting ID*: 881 0067 6046 *Passcode*: 680246 - - - Maurizia Rossi Dipartimento di Matematica e Applicazioni Università di Milano-Bicocca

Ulteriori informazioni alla pagina http://datascience.maths.unitn.it/events/rl2021/ The Department of Mathematics at the University of Trento organises within the Master's program in Mathematics, track Mathematics for Data Science, the crash course Reinforcement Learning: the way machines learn held by Prof. Maurizio Parton (University of Chieti-Pescara), on Jan. 27 and 29, and Feb. 3 and 5, 2021. The course will take place online and will be given in English. Participation is free of charge, but registration is required. To register, send an email to luigiamedeo.bianchi(a)unitn.it The number of places available for external participants is limited. Abstract: Reinforcement Learning (RL) is a machine learning technique where an agent learns to solve a decision problem by performing actions and assessing their results. RL has been acknowledged as a breakthrough technology by MIT in 2017. We will study the fundamentals of RL and will sketch the latest methods used to solve a variety of complex tasks, from gaming to computer science, finance, and robotics. This is a 12h crash course intended for students with a background in probability. The course is comprised of theory, applications and assignments. Some experience with Python may prove useful to fully profit from the exercises and assignments.

Padova Online Seminar by Giacomo Di Gesù (Università di Pisa) [Friday, Jan. 15 at 14.30]
by alessandra bianchi 07 Jan '21

07 Jan '21

Dear Colleagues, We would like to invite you to the following Probability seminar that will take place on January 15 at 14.30 by the zoom platform. ________________________________________________________ Speaker: Giacomo Di Gesù (Università di Pisa) Title: Metastability for an SPDE via functional inequalities 15 JANUARY (Friday) - 14:30 zoom link: TBA (available on the webpage https://www.math.unipd.it/~bianchi/seminari/ ) Abstract: We consider a small perturbation by space-time Gaussian white noise of the Allen-Cahn equation. The latter is a nonlinear PDE, which can be seen as a gradient flow with respect to a double-well potential. The perturbed stochastic evolution is then a paradigmatic model exhibiting metastable dynamics: before exploring the full state space and reaching equilibrium, the system remains localized at the bottom of one well for a very long time. In the talk I will present a general approach to get metastability estimates in this infinite-dimensional setting. The focus is on sharp estimates that go beyond rough large deviation asymptotics and that are crucial for deriving coarse-grained effective dynamics. A key ingredient of the method is the systematic use of log-Sobolev inequalities in order to lift tunnelling calculations to infinite dimensions. As a main application we show how to compute the leading asymptotic behavior of the exponentially small spectral gap. We obtain an explicit formula expressed in terms of a certain Fredhom determinant as prefactor. This result shows that the gap behaves like the inverse of the average tunnelling time between wells and provides an alternative, spectral-theoretic way to prove the Eyring-Kramers formula. Based on joint work with Morris Brooks (IST Austria). -- 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/
