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.

Seminar prof. Kohatsu-Higa at DISIM - University of L'Aquila
by Fabio Antonelli 27 Apr '23

27 Apr '23

Whoever is interested is welcome: We are pleased to announce that on Wednesday May 3rd 2023 at 2:30 p.m. at DISIM- University of L'Aquila - classroom A.1.6 (Coppito 0) Via Vetoio SNC - L'Aquila and online at the link (Join Zoom Meeting): https://ritsumei-ac-jp.zoom.us/j/99895927770?pwd=ZFEwc2FwU0VmdUJaZiszaTFsUE… Meeting ID: 998 9592 7770 Passcode: 273749 Prof. Arturo Kohatsu-Higa Department of Mathematical Sciences Ritsumeikan University 1-1-1 Nojihigashi, Kusatsu, Shiga, 525-8577, Japan Will give the talk: Can we differentiate a stopping time? Abstract: In various situations, one may be interested in the concept of differentiation of random variables or processes with respect to some underlying parameters. We will discuss this possibility in the case of random variables related to stopping times. Rather than discussing general theory (which we may), we will present basic examples that give hints about the general results and exhibit the difficulties involved in the development of general results. ________________________________ Fabio Antonelli DISIM - Università di L'Aquila
