Corso di dottorato di Amine Asselah in Sapienza
by Lorenzo Taggi 22 May '23

22 May '23

Si annuncia il corso di dottorato su *Random Walks e Branching Random Walks* del professor Amine Asselah (università di Parigi-Est Créteil) presso il dipartimento di Matematica di Sapienza Università di Roma. Si riportano l’abstract e il calendario, in allegato il programma dettagliato. Si prega di diffondere l’annuncio a possibili interessati. Per essere inseriti nella mailing list del corso e essere aggiornati su possibili variazioni del calendario si prega di inviare un'email a lorenzo.taggi(a)uniroma1.it *ABSTRACT:* Simple Random Walk is the first example of a Markovian process, whereas Branching Random Walk has a time indexed by a random tree, and looses the SRW’s sequential way of visiting space. The highlights of the course would be two phenomena in high dimensions linked with folding. - The chances that two independent walks meet for a long time. - The chances that two independent branching walks both visit a large region, and this is to be discovered during the course. We plan to have self-contained lectures (with little pre-requisites), and will start with reviewing useful facts (classical and not) on random walks. *CALENDARIO:* Tutte le lezioni hanno luogo dalle 11:00 alle 13:00 presso il dipartimento di Matematica in aula B nei seguenti giorni: Lez. 1: lunedì 29/5 Lez. 2: giovedì 1/6 Lez. 3: giovedì 8/6 Lez. 4: venerdì 9/6 Lez. 5: lunedì 12/6 Lez. 6: giovedì 15/6 Lez. 7: lunedì 19/6 Lez. 8: giovedì 22/6

seminario Francois Baccelli 24 maggio
by Daniela De Canditiis 21 May '23

21 May '23

Buongiorno a tutti, il prossimo appuntamento del ciclo Seminari generali IAC si terrà Mercoledì 24 Maggio ore 14:30 sul Canale Youtube Cnr-IAC al link https://www.youtube.com/watch?v=JgsmwZg7eAg con Francois Baccelli Title High dimensional stochastic geometry in the Shannon regime Abstract This talk will focus on Euclidean stochastic geometry in the Shannon regime. In this regime, the dimension n of space tends to infinity, point processes have intensities which are exponential functions of n, and the random compact sets have diameters of order square root of n. Three basic models of stochastic geometry based on Poisson processes will be considered: the Boolean model, the Poisson-Voronoi tessellation and the Poisson hyperplane tessellation. We will show how to calculate the asymptotic behavior of the classical quantities of stochastic geometry for these three models in the Shannon regime: for the Boolean model, the volume fraction, the percolation threshold or the size of the connected components; for tessellations, statistics of geometric properties of cells (volume, diameter, etc.). These questions are motivated by problems in information theory, including the calculation of error exponents for channel coding based on random codes and calculating the distortion in the one-bit compression-based source coding. Survey of work in collaboration with Venkat Anantharam (UC Berkeley) and Eliza O'Reilly (Caltech).

SPASS Seminar: Francesco Russo
by Andrea Agazzi 19 May '23

19 May '23

Dear Colleagues, We would like to invite you to the following SPASS <https://sites.google.com/unipi.it/spass> seminar, jointly organized by UniPi, SNS, UniFi and UniSi: *Semimartingales with jumps, weak Dirichlet processes and path-dependent martingale problems* by *Francesco Russo* (ENSTA-Paris) The seminar will take place on *TUE, 23.05.2023* at *14:00 CET* in Aula Seminari, Department of Mathematics, University of Pisa and streamed online here <https://meet.google.com/gji-phwo-vbg>. The organizers, A. Agazzi, G. Bet, A. Caraceni, F. Grotto, G. Zanco https://sites.google.com/unipi.it/spass -------------------------------------------- *Abstract: In this talk we will revisit the notion of weak Dirichlet process which is the natural extension of semimartingale with jumps. If X is such a process, then it is the sum of a local martingale M and a martingale ortogonal process A in the sense that [A, N] = 0 for every continuous local martingale N . We remark that if [A] = 0 then X is a Dirichlet process. The notion of Dirichlet process is not very suitable in the jump case since in this case A is forced to be continuous.The talk will discuss the following points.1. To provide a (unique) decomposition which is also new for semimartingales with jumps.2. To discuss some new stability theorem for weak Dirichlet processes through C^{0,1} transformations.3. To discuss various examples of such processes arising from path-dependent martingale problems. This includes path-dependent stochastic differential equations involving a distributional drift and with jumps.The talk is based on a joint paper with E. Bandini (Bologna).*

Seminar: Rongfeng Sun at Tor Vergata
by Michele Salvi 18 May '23

18 May '23

Dear all, On Wednesday, May 24th, at 14h00 in Aula 2001 (change of usual place! Aula 2001 is on the top floor of the Math Department, close to the copy shop) at Roma Tor Vergata, RoMaDS (https://www.mat.uniroma2.it/~rds/about.php) will host Rongfeng Sun (NUS Singapore) with the seminar “A new correlation inequality for Ising models with external fields" Abstract: We study ferromagnetic Ising models on finite graphs with an inhomogeneous external field. We show that the influence of boundary conditions on any given spin is maximised when the external field is identically 0. One corollary is that spin-spin correlation is maximised when the external field vanishes. In particular, the random field Ising model on Z^d, d ≥ 3, exhibits exponential decay of correlations in the entire high temperature regime of the pure Ising model. Another corollary is that the pure Ising model on Z^d, d ≥ 3, satisfies the conjectured strong spatial mixing property in the entire high temperature regime. Based on joint work with Jian Ding and Jian Song. We encourage in-person partecipation. Should you be unable to come, here is the link to the Teams streaming: https://teams.microsoft.com/l/meetup-join/19%3arfsL73KX-fw86y1YnXq2nk5VnZFw… . The seminar is part of the Excellence Project MatMod@TOV.
