(PMS)^2 talk: J.-D. Deuschel [4 May] at UniMIB
by Maurizia Rossi 03 May '23

03 May '23

Dear colleagues, We are happy to announce the following *hybrid* - that is, in person with online streaming - talk: Speaker: *Jean-Dominique Deuschel* (TU Berlin) *Title: *An isomorphism theorem for Ginzburg-Landau interface models and scaling limits. (See Abstract below.) *Date and Time:* Thursday May 4, 16:30-17:30 (Rome time zone). Place: *Aula 3014, Dip. di Matematica e Applicazioni, Univ. di Milano-Bicocca*, Via R. Cozzi 55, Milano. *Webex link:* https://unimib.webex.com/unimib-it/j.php?MTID=mc07da73e64ea2eb0da78975bc808… *Meeting number:* 2741 491 0178*Password: *HPxNQASR579 (47967277 for phones) %%%%%%%%%% *Abstract: *We introduce a natural measure on bi-infinite random walk trajectories evolving in a time-dependent environment driven by the Langevin dynamics associated with a gradient Gibbs measure with convex potential. We derive an identity relating the occupation times of the Poissonian cloud induced by this measure to the square of the corresponding gradient field, which - generically - is not Gaussian. In the quadratic case, we recover a well-known generalization of the second Ray-Knight theorem. We further determine the scaling limits of the various objects involved in dimension 3, which are seen to exhibit homogenization. In particular, we prove that the renormalized square of the gradient field converges under appropriate rescaling to the Wick-ordered square of a Gaussian free field on R^3 with suitable diffusion matrix, thus extending a celebrated result of Naddaf and Spencer regarding the scaling limit of the field itself. (Based on joint work with Pierre-François Rodriguez.) %%%%%%%%%%% This talk is part of the *(PMS)^2: Pavia-Milano Seminar series on Probability and Mathematical Statistics* organized jointly by the universities Milano-Bicocca, Pavia, Milano-Politecnico.

Buongiorno, ricevo e con piacere inoltro. Saluti Alessandra ---------- Forwarded message --------- From: Serena Cenatiempo <serena.cenatiempo(a)gssi.it> Date: Wed, 3 May 2023 at 08:01 Subject: GSSI Math Colloquium by Daniel Ueltschi / May 4th at 14.00 To: Alessia Nota <alessia.nota(a)univaq.it> Dear all of the SMAQ group, this is to announce that Daniel Ueltschi will give a Colloquium talk at GSSI on *Loop models and the universal distribution of the loop lengths* this Thursday*, May 4th, 2023 at 14.00 in the **GSSI Auditorium (please NOTICE the unusual time).* The talk will be also streamed online at the link below: https://zoom.us/j/97365002731?pwd=cmR1Y0RIV3lxTlJ5QWVJUlN0akNvQT09 ID riunione: 973 6500 2731 Passcode: MATHatGSSI Abstract. I will review several models that consist of one-dimensional loops living in the three-dimensional space. These models describe bosonic systems, and classical or quantum spin systems. Their common feature is that the joint distribution of their loop lengths has universal behaviour: It is always a Poisson-Dirichlet distribution. Most of this theory is conjectural, but it is backed by numerical studies and some partial rigorous results.

PMS^2 hybrid talk: Davide Addona, Monday May 8 at 16.30.
by Margherita Zanella 02 May '23

02 May '23

Dear colleagues, we are happy to announce the hybrid - that is, in person with online streaming - talk of the (PMS)^2 series: Speaker: Davide Addona (Università di Parma) Title: Young equations in infinite dimension with singularities. Abstract: In this talk I will present some new results about Young differential equations in infinite dimension with “non smooth” initial datum. During the talk I will introduce the concept of Young integral for non smooth paths defined by Young in 1936 and an algebraic approach to integration with respect to non smooth paths due to Gubinelli in 2004, whose generalization allows to consider abstract Cauchy problems driven by an irregular path. At last, if I will have time, I will give an idea of the of the theory of rough paths started by Terry Lions in 1998 and developed by other authors in the last twenty years. Date and time: Monday May 8, 16:30-17:30 (Rome time zone). Place: Aula Seminari - III piano (third floor), Dipartimento di Matematica, Politecnico di Milano, Piazza Leonardo da Vinci, 32 – 20133 Milano - Ed. 14 “Nave” Campus Bonardi. (Accesso pedonale da: Via A.M. Ampère, 2 - Milano, Via E. Bonardi, 9 - Milano, Via G. Ponzio, 31 - Milano).

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.
