SPASS Seminar: Mauro Mariani
by Francesco Grotto 02 May '23

02 May '23

Dear Colleagues, We would like to invite you to the following SPASS seminar, jointly organized by UniPi, SNS, UniFi and UniSi: Random currents and homologies on compact manifolds Mauro Mariani (National Research University Moscow) The seminar will take place on TUE, 9.5.2023 at 14:00 CET in Sala Seminari, Dipartimento di Matematica, Pisa and streamed online at the link below. The organizers, A. Agazzi, G. Bet, A. Caraceni, F. Grotto, G. Zanco https://sites.google.com/unipi.it/spass -------------------------------------------- *Abstract: * We study the long time behavior of stochastic currents associated to diffusion processes on compact Riemannian manifolds. In the first part of the talk, sharp results about existence and tightness of stochastic currents will be discussed. In the second part, some problems related to random homologies (homology class associated to the paths of diffusion processes) will be addressed. In particular, we give a full geometric characterization of manifolds such that the associated random homology has a gaussian asymptotic. Some simpler related problems (Gallavotti-Cohen symmetry, relation with the Riemannian metric).

De Finetti Risk Seminar - May 3, 2023
by Emanuela Rosazza Gianin 29 Apr '23

29 Apr '23

On behalf of the Scientific Committee of the "B. de Finetti Risk Seminars, Milano Lectures on the Mathematical Theory of Economics and Finance”, we are glad to invite you to participate at the following Lecture: Jean-Pierre Fouque University of California Santa Barbara Title: Reinforcement Learning Algorithm for Mixed Mean Field Control Games Abstract: We present a new combined Mean Field Control Game (MFCG) problem which can be interpreted as a competitive game between collaborating groups and its solution as a Nash equilibrium between the groups. Within each group the players coordinate their strategies. An example of such a situation is a modification of the classical trader's problem. Groups of traders maximize their wealth. They are faced with transaction cost for their own trades and a cost for their own terminal position. In addition they face a cost for the average holding within their group. The asset price is impacted by the trades of all agents. We propose a reinforcement learning algorithm to approximate the solution of such mixed Mean Field Control Game problems. We test the algorithm on benchmark linear-quadratic specifications for which we have analytic solutions. Joint work with A. Angiuli, N. Detering, Mathieu Laurière, and J. Lin. LOCATION: The seminar will be held on *May 3, *2023 at *18.00,* Aula Di Rappresentanza, Dipart. Matematica, Università di Milano, Via Saldini 50, Milano.

Seminar Prof. F. Patras at Università degli Studi di Milano
by Stefania Ugolini 28 Apr '23

28 Apr '23

Professor F. Patras (Univ. Côte d’Azur, CNRS) will give a seminar on Thursday, May 04th at 15:00, in Aula Dottorato, at the Department of Mathematics "Federigo Enriques", Università degli Studi di Miano. Title: "Wick polynomials, from classical to free probability." Abstract: Wick polynomials are a central object in quantum physics and classical probability (where they encode for example "chaos decompositions" - they provide an orthonormal basis of the space of square integrable functions of a Gaussian random variable). We will discuss an algebraic formulation of Wick's constructions that allows to generalize them to a wide variety of contexts, featuring free probability - a probability theory closely linked to random matrices but that appears in various recent works, in different areas.
