Seminar presented by Marta Leocata - Applications of Probability to Economics
by Enrico Scalas 24 Jun '25

24 Jun '25

Dear colleagues, (With apologies for cross-posting) On 26 June 2025 at 2pm (CET) Marta Leocata (LUISS Guido Carli, Department of AI, Data and Decision Sciences) will present an online seminar whose title is: Two applications of multi-agent models in economic and social systems Abstract: In this talk, we present an overview of mathematical models that capture the behavior of myopic agents—who rely on short-term, local information in their decision-making—and strategic agents, who consider the long-term consequences of their actions within interactive environments. These concepts will be illustrated through two applications in economic and social contexts: a multi-agent model for the co-evolution of preferences and actions in the emergence of social norms (joint work with Michele Aleandri, LUISS, and Laura Marcon, CNR), and a Mean Field Game approach to the Emission Trading System (joint work with Giulia Livieri, LSE, and Gianmarco Del Sarto, TU Darmstadt). The seminar link is: https://uniroma1.zoom.us/j/87022289921 This is the first seminar of a series of three seminars organised by UMI-PRISMA on the Applications of Probability to Economics in preparation to the 2025 Summer School of Mathematics for Economic and Social Sciences: https://indico.sns.it/event/105/overview The next seminars will be: on 10 July 2025, Annamaria Olivieri, (University of Parma (Italy), Department of Economics and Management), Modelling Stochastic Mortality for Life Insurance Applications on 17 July 2025, Sara Merino Aceituno (Faculty of Mathematics, University of Vienna, Austria), Large particle limit for jump processes Everybody is welcome to join these seminars!

After a brief discussion of the nature of maths today, we wish to recall some historical facts that go back to the dawn of mathematics and that emphasize the fast growing role of mathematics with the use of computers and machine learning (AI). We shall describe how real world problems are being tacked with the help of mathematical models and equations that are often partial differential equations. And we wish to emphasize how the study of applications goes hand in hand with the development of maths. We will do so by discussing, without mathematical details, examples using Mean Field Games theory or random matrices.

Seminario CNR-IAC
by GIOVANNI LUCA TORRISI 24 Jun '25

24 Jun '25

Oggi, martedì 24 giugno 2025 alle ore 14:30 Dario Trevisan, Dipartimento di Matematica , Università di Pisa , terrà il seminario: Convergenza quantitativa delle reti neurali profonde ai processi gaussiani Astratto In questo seminario, esploriamo la convergenza quantitativa di ampie reti neurali profonde con pesi gaussiani a processi gaussiani, stabilendo nuove velocità per la loro approssimazione gaussiana. Mostriamo che la distanza di Wasserstein tra l'output della rete e la sua controparte gaussiana scala inversamente alla larghezza della rete, con limiti applicabili a qualsiasi insieme finito di input in specifiche condizioni di non degenerazione delle covarianze. Inoltre, estendiamo la nostra analisi al framework bayesiano, studiando i posteriori esatti per le reti neurali, quando dotate di priori gaussiani e funzioni di verosimiglianza regolari, ma forniamo anche recenti progressi nell'approssimazione quantitativa di reti addestrate tramite discesa del gradiente nel regime NTK. Basato su lavori congiunti con A. Basteri, A. Agazzi ed E. Mosig. Il seminario si svolgerà presso la sede CNR-IAC di Roma , sala al primo piano , in modalità mista: in presenza e in streaming al link https://www.youtube.com/watch?v=RMKVBN5l13g Cordialmente, Giovanni Luca Torrisi

Si segnalano i seguente seminario a tutti gli interessati. ----------------------------------------------------------------------------------------------------- Martedì 24 Giugno 2025, ore 15:00. Aula Seminari III Piano, Dipartimento di Matematica, Politecnico di Milano. Speaker: Giorgio Cipolloni, The University of Arizona, College of Mathematics. Title: Spectral Statistics of Large Random Matrices Abstract: The last fifteen years have brought major breakthroughs in understanding the spectra of large random matrices. I'll discuss several recent advances in eigenvalue and eigenvector statistics for both Hermitian and non-Hermitian matrices, focusing on the universal patterns that emerge.

Aula Seminari III Piano, Dipartimento di Matematica, Politecnico di Milano. Speaker: Giorgio Cipolloni, The University of Arizona, College of Mathematics. Title: Logarithmically Correlated Fields from Random Matrices. Abstract: In 2012, Fyodorov, Hiary, and Keating discovered a new connection between random matrices and extremal values of logarithmically correlated fields, such as branching Brownian motion and the 2D Gaussian Free Field. In particular, they conjectured that extreme statistics of random characteristic polynomials of unitary matrices belong to the universality class of logarithmically correlated fields, which was first identified by Bramson in his seminal work on branching Brownian motion. I will review several contributions in proving this connection and present some new recent works establishing new connections of characteristic polynomials of non-Hermitian matrices and two- and three-dimensional logarithmically correlated fields.
