Seminario Jacopo Borga, Martedì 11 Febbraio, Sapienza Università di Roma
by Silvestri, Vittoria 11 Feb '25

11 Feb '25

Segnalo il seguente seminario, che si terrà Martedì prossimo in Sapienza. *Martedì 11 Febbraio, ore 14:00,* Sala di Consiglio, Dipartimento di Matematica, Sapienza Università di Roma *Speaker:* Jacopo Borga (MIT) *Title: *Lattice Yang-Mills theory in the large N limit via sums over surfaces *Abstract:* Lattice Yang-Mills theories are important models in particle physics. They are defined on the d-dimensional lattice Z^d using a group of matrices of dimension N, and Wilson loop expectations are the fundamental observables of these theories. Recently, Cao, Park, and Sheffield showed that Wilson loop expectations can be expressed as sums over certain embedded bipartite maps of any genus. Building on this novel approach, we prove in the so-called strongly coupled regime: - A rigorous formula in terms of embedded bipartite planar maps of Wilson loop expectations in the large N limit, in any dimension d. - An exact computation of Wilson loop expectations in the large N limit, in dimension d=2, for a large family of (simple and non-simple) loops. Previous results to the two aforementioned points were previously established by Chatterjee (2019) and Basu & Ganguly (2016), respectively. Our results extend these previous results, offer simpler proofs and provide a new perspective on these significant quantities. This work is a collaboration with Sky Cao and Jasper Shogren-Knaak. ******************************** Vittoria Silvestri Assistant Professor Department of Mathematics University "La Sapienza" Piazzale Aldo Moro, 5 00185 - Rome ********************************

SPASS Seminar: Olga Ariasova
by Francesco Grotto 10 Feb '25

10 Feb '25

Dear Colleagues, We would like to invite you to the following SPASS seminar, jointly organized by UniPi, SNS, UniFi and UniSi: *Homogenization of a multivariate diffusion with semipermeable reflecting interfaces* by Olga Ariasova (Inst. Geophys. Nat. Acad. Sciences of Ukraine, F. Schiller Univ. of Jena) The seminar will take place tomorrow TUE, 11.2.2025 at 14:00 CET in Aula Seminari, Dipartimento di Matematica, UNIPI and streamed online at the link below. The organizers, G. Bet, A. Caraceni, F. Grotto, G. Zanco https://sites.google.com/unipi.it/spass *---------------------------------------------------------* *Abstract: * The mathematical problem of homogenization typically involves studying the effective parameters of a system that exhibits rapid variations in its spatial characteristics. However, we focus on a stochastic multivariate homogenization problem of a different kind: the diffusion in the presence of narrowly located semipermeable interfaces. In simple words, our model reminds of a foiled composite material consisting of a media interlaced with very thin plates of different permeability. In material science such models are referred to as reinforced materials like a glass wool reinforced by aluminium foil. Usually, one is interested in the effective parameters of such a system. By combining the study of stochastic differential equations with local times and homogenization, we explore how the presence of interfaces can alter the diffusion behavior of the limit process. As a byproduct of our research, we obtain theorems for the existence and uniqueness of solutions to SDEs for multidimensional diffusion processes with membranes. Uniqueness is a problem of particular interest because it implies the strong Markov property of the solution, which is essential for the proof of convergence.

SEMINARS IN STATISTICS @ COLLEGIO CARLO ALBERTO <https://www.google.com/url?q=https://www.carloalberto.org/events/category/s…> Venerdì 14/02/2025, presso il Collegio Carlo Alberto, in Piazza Arbarello 8, Torino, si terrà il seguente seminario: ------------------------------------------------ 12.00-13.00 Speaker: Yufei ZHANG (IMPERIAL COLLEGE LONDON) Title: Towards sample-efficient continuous-time reinforcement learning Abstract: Recently, reinforcement learning (RL) has garnered significant research interest. However, much of this attention and success has been focused on the discrete-time setting. RL for continuous-time systems, despite its natural applicability to a wide range of control tasks in physical systems, remains largely unexplored with limited progress. In particular, characterizing the sample efficiency of continuous-time RL algorithms continues to be a challenging and open problem. In this talk, we introduce a principled framework for systematically analyzing regret bounds for continuous-time RL algorithms in episodic model-based settings. Our framework decomposes the regret analysis into two fundamental components: the finite-sample accuracy of model estimation and the performance gap of a greedy policy derived from the estimated models. The finite-sample accuracy is analyzed using filtering theory and concentration inequalities for correlated observations, while the performance gap is quantified by leveraging the robustness of the control problem. By integrating these insights, we optimize the exploration-exploitation trade-off, achieving the best-known sample complexity in the current literature. ------------------------------------------------ Sarà possibile il seminario anche in streaming: chiunque volesse collegarsi è pregato di inviare una email entro *mercoledì 12/02/2025* a matteo.giordano(a)unito.it <mailto:matteo.giordano@unito.it>.

Seminario Raphael Huser presso Politecnico di Milano

Si avvisa che in data 10-02-2025, alle ore 14:30 presso il Politecnico di Milano, Edificio 16B (Via Bonardi 9), in Aula 16B.0.1 (piano terra), nell’ambito delle attività del MOX, si svolgerà il seguente seminario: Raphael Huser, KAUST - King Abdullah University of Science and Technology Titolo: Neural Inference Methods for Spatial Extremes in High Dimensions Abstract: Neural Bayes estimators are neural networks that approximate Bayes estimators. They are thus likelihood-free, extremely fast to evaluate, and amenable to rapid uncertainty quantification, while also (approximately) inheriting the appealing large-sample properties of Bayes estimators. Neural Bayes estimators are therefore ideal to use with spatial extremes models observed in high dimensions, where estimation is often a computational bottleneck. In this seminar, I will summarize our research progress in that area and explain how, for any spatial model that can be simulated from, a single neural Bayes estimator can be trained to make fast inference with new data that involve varying sample sizes, varying spatial configurations of observed locations, and varying censoring levels used in peaks-over-threshold modeling. This methodology will be illustrated by application to sea surface temperature extremes over the Red Sea, and air pollution extremes over the whole Arabic peninsula. Joint work with Jordan Richards, Matthew Sainsbury-Dale, and Andrew Zammit-Mangion. This initiative is part of the “Ph.D. Lectures” activity of the project "Departments of Excellence 2023-2027" of the Department of Mathematics of Politecnico di Milano.

Speaker: Benedetta Ferrario, Università di Pavia. Title: Soluzioni statistiche stazionarie per un'equazione di Schrödinger non lineare. Abstract: Per un'equazione deterministica di Schrödinger si mostra l'esistenza di soluzioni statistiche stazionarie ottenute come opportuno limite della soluzione della corrispondente EDP perturbata con una forzante stocastica e una dissipazione lineare. Inoltre si analizzano le proprietà di questi processi stazionari.

AMIS - mailing list per Applications of Mathematics in Industry and Society (PE1_22)
by Marco LI CALZI 05 Feb '25

05 Feb '25

Cari Random-isti/e, da pochi giorni è attiva una mailing list denominata AMIS (Applications of Mathematics in Industry and Society). Ispirandosi a quanto fa Random per la probabilità, AMIS è dedicata a comunicazioni per la comunità di matematici con interessi di ricerca, didattici o divulgativi che intersecano i temi del Panel ERC PE1_22 (Applications of Mathematics in Industry and Society). AMIS in francese sta per “amici” (matematici): la lista è aperta a tutti gli interessati e vi invitiamo a iscrivervi, seguendo le semplici istruzioni in calce. Per mitigare possibili abusi, la lista è moderata: ciascuno può inviare messaggi (in inglese o in italiano) che sono inoltrati senza modifiche dopo l’approvazione del moderatore (che è il segretario dell’Amases). Cordialmente, marco licalzi. ______________________________ Marco Li Calzi Presidente AMASES: Associazione per la Matematica Applicata alle Scienze Economiche e Sociali ______________________________ INDICAZIONI OPERATIVE 1. Iscriversi ad AMIS Inviare un’email (anche priva di testo) ad amis-subscribe(a)amases.org <mailto:amis-subscribe@amases.org> e seguire le istruzioni ricevute automaticamente via email poco dopo. 2.

Double seminar: Alexandre Stauffer & Jacopo Borga at Tor Vergata 10.02
by Michele Salvi 05 Feb '25

05 Feb '25

Dear all, On Monday, February 10th, at 14h00 in Aula Dal Passo of Tor Vergata Math Department, RoMaDS <https://www.mat.uniroma2.it/~rds/events.php> will host a double seminar by Alexandre Stauffer (King's College London) and Jacopo Borga (MIT). See below for titles and abstracts. 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…"Tid"%3a"24c5be2a-d764-40c5-9975-82d08ae47d0e"%2c"Oid"%3a"650fc4a8-4cec-4bd2-87bc-90d134074fe6"} <https://teams.microsoft.com/l/meetup-join/19%3arfsL73KX-fw86y1YnXq2nk5VnZFw…> The seminars are part of the Excellence Project MatMod@TOV. TALK 1 Alexandre Stauffer (King's College London) “Non-monotone phase transition in interacting particle systems” In this talk we will discuss a reaction-diffusion particle system which has a non-monotone phase transition. I will explain the techniques used to analyze monotone models and how they can be refined to analyze non-monotone particle systems. Based on upcoming works with Leandro Chiarini and Tom Finn. TALK 2 Jacopo Borga (MIT) “Lattice Yang-Mills theory in the large N limit via sums over surfaces" Abstract: Lattice Yang-Mills theories are important models in particle physics. They are defined on the d-dimensional lattice Z^d using a group of matrices of dimension N, and Wilson loop expectations are the fundamental observables of these theories. Recently, Cao, Park, and Sheffield showed that Wilson loop expectations can be expressed as sums over certain embedded bipartite maps of any genus. Building on this novel approach, we prove in the so-called strongly coupled regime: - A rigorous formula in terms of embedded bipartite planar maps of Wilson loop expectations in the large N limit, in any dimension d. - An exact computation of Wilson loop expectations in the large N limit, in dimension d=2, for a large family of (simple and non-simple) loops. Previous results to the two aforementioned points were previously established by Chatterjee (2019) and Basu & Ganguly (2016), respectively. Our results extend these previous results, offer simpler proofs and provide a new perspective on these significant quantities. This work is a collaboration with Sky Cao and Jasper Shogren-Knaak.
