Saluti Alessandra ---------- Forwarded message --------- From: Teta, Alessandro <teta(a)mat.uniroma1.it> Date: Mon, 5 May 2025 at 17:17 Subject: Seminario di Matematica, Scienza & Società To: Alessandra Faggionato <faggiona(a)mat.uniroma1.it> Avviso di seminario di Matematica, Scienza & Società Lunedì 12 maggio 2025, alle ore 17.00 Aula Picone del Dipartimento di Matematica G. Castelnuovo di Sapienza Università di Roma *Andrea Rinaldo (École Polytechnique Fédérale Lausanne & Università di Padova)Clima, acqua, malattie e solidarietá nel mondo che cambia* Sommario Il clima sta cambiando rapidamente. Dobbiamo farlo anche noi, non considerando scontati privilegi consolidati dal tempo, usi e tradizioni dei luoghi, organizzazioni politiche e sociali, e le espressioni della sensibilità collettiva. Serviranno letture attente del governo dell’acqua, riflettendo su Ambiente naturale e costruito intorno a noi, e ripensamenti del rapporto fra risorse e solidarietà, e sui modi e i tempi della giustizia distributiva nella gestione delle risorse idriche. La mia tesi: i grandi temi di salvaguardia legati al governo dell’acqua, e dunque alla metastoria, riguardano sia il Nord che del Sud del mondo, e ci obbligano a riflettere sulla relazione fra trasformazioni del paesaggio, usi del suolo e dinamica delle risorse naturali, ma anche su un’etica dello sviluppo che tenga conto di un’equa distribuzione dei privilegi e delle risorse. Il seminario si propone in particolare di evidenziare il filo rosso che lega la descrizione matematica di processi idrologici ed epidemiologici, e della geometria della natura nel paesaggio fluviale, a temi centrali nella valutazione della ricchezza e della povertà delle nazioni e nella economia ambientale contemporanea. Per le registrazioni dei seminari già svolti e altre informazioni visita il sito https://sites.google.com/view/alessandro-teta/matematica-scienza-e-societa?… I seminari di Matematica, Scienza e Società sono dedicati all'approfondimento storico e critico di aspetti della matematica e dei suoi rapporti con la scienza e con la società. I seminari hanno carattere interdisciplinare e sono rivolti a studenti, dottorandi, docenti universitari e docenti della scuola secondaria di secondo grado. F. Dell'Isola, M. Pulvirenti, E.

Seminario PRISMA lunedì 5 maggio 2025 - C. Orrieri & L. Scarpa
by Sonia Mazzucchi 05 May '25

05 May '25

Buongiorno, ricordiamo a tutti gli interessati che oggi lunedì 5 maggio dalle 16 alle 17:17 si svolgerà il periodico seminario online del gruppo UMI-PRISMA. I seminari PRISMA hanno un formato di "colloquium" per creare un'occasione di scambio e discussione con tutta la comunità dei probabilisti e statistici italiani. Ogni giornata comprende due relatori che tengono due seminari di 30 minuti strettamente connessi, per presentare alla comunità una prospettiva sul proprio ambito di ricerca. Da quest'anno le registrazioni dei seminari vengono pubblicate sul canale YouTube dell'UMI: https://youtube.com/playlist?list=PLmySpc-jrtAMq84VH71evyqPc1hl6eEQb I relatori di oggi pomeriggio saranno Carlo Orrieri (Università di Pavia) e Luca Scarpa (Politecnico di Milano) che parleranno di: Equazioni stocastiche doppiamente nonlineari e relativi problemi di regolarizzazione per rumore con il seguente orario: 16:00 Primo seminario 16:30 Pausa e discussione 16:45 Secondo seminario 17:15 Conclusione e discussione Trovate di seguito il riassunto. I seminari verranno trasmessi via Zoom al seguente link: https://unitn.zoom.us/j/88514293418 <https://www.google.com/url?q=https://unitn.zoom.us/j/88514293418&sa=D&sourc…> ID riunione: 885 1429 3418 Codice d’accesso: 236100 Vi aspettiamo numerosi! Alberto Chiarini e Sonia Mazzucchi %%%%%%%%%%%%%%%%%%%%%%%%%%%% RELATORI: Carlo Orrieri (Università di Pavia) e Luca Scarpa (Politecnico di Milano) TITOLO: Equazioni stocastiche doppiamente nonlineari e relativi problemi di regolarizzazione per rumore RIASSUNTO: Nella prima parte del seminario verranno introdotte alcune classi di equazioni di evoluzione in relazione alla modellizzazione di problemi di transizione di fase. Dal punto di vista matematico tali equazioni sono caratterizzate da una dinamica doppiamente nonlineare che tipicamente non ne assicura la buona positura. In particolare, l’unicità delle soluzioni viene a mancare. Questo motiva l’introduzione e l'analisi di opportune formulazioni stocastiche per tali modelli, nell’ottica di ottenere effetti di regolarizzazione per rumore. Nella seconda parte il problema di regolarizzazione per rumore verrà inquadrato nel contesto più generale di equazioni di evoluzione stocastiche con drift singolare e verranno presentati alcuni risultati di unicità. L'applicabilità di tali tecniche identificherà naturalmente un concetto di criticità che porrà le equazioni doppiamente nonlineari in un regime supercritico. Per queste verrà fornito infine un risultato parziale di stabilità per rumore. I risultati presentati nei seminari sono stati ottenuti in collaborazione con F. Bertacco (Imperial College London) e U. Stefanelli (Università di Vienna). %%%%%%%%%%%%%%%%%%%%%%%%%%%%

Dear all, I am glad to announce and invite you to the following seminar Statistics Seminars 2024/2025 Thursday May 8th, 2025 at 14.30 Room IV in Via Belle Arti, 41, Department of Statistics, University of Bologna or online on Microsoft Teams (here below you can find the link) “A world of copulas” Prof. Roberto Ghiselli Ricci (Università Ca‘ Foscari Venezia) Abstract A journey into the most outstanding family of aggregation functions given by the Copulas. They are particularly intriguing, because, on the one hand, they offer a theoretically fertile field of study with deep connections with different branches of mathematics such as Differential Calculus and even Group Theory, and, on the other hand, as consequence of the seminal Sklar's Theorem (1969), they are an essential tool for building refined stochastic models able to satisfy properties required by real problems.

SPASS Seminar: Theodore Drivas
by Mario Maurelli 02 May '25

02 May '25

Dear Colleagues, We would like to invite you to the following SPASS seminar, jointly organized by UniPi, SNS, UniFi and UniSi (abstract below): *Vibrodynamics of constrained mechanical systems* by *Theodore D. Drivas* (Stony Brook University) The seminar will take place on *TUE, 06.05.2025* at *9:00 CEST *(mind unusual time) in Aula Seminari, Dipartimento di Matematica, UNIPI and streamed online at this link <https://meet.google.com/gji-phwo-vbg>. Best regards Mario Maurelli https://sites.google.com/unipi.it/spass <https://www.google.com/url?q=https://sites.google.com/unipi.it/spass&source…> -------------------------------------------- *Title: Vibrodynamics of constrained mechanical systems* *Abstract: We study the effect of rapid vibration of constraining surfaces of arbitrary codimension on a confined mechanical particle. The slow dynamics experience an effective potential force coming from the geometry of the vibrating surface, which can introduce new equilibria and change stability character of existing ones. A classical example is Kapitza's stabilization of the inverted pendulum with a vibrating pivot. After developing this formalism for finite dimensional systems, we generalize to infinite dimensions by analogy and study the resulting vibrogenic forces for inextensible threads and incompressible fluids. The thread effectively becomes elastic, and the fluid evolves as a variant of the incompressible inhomogeneous system. This is joint work with D. Glukhovskiy.*

Cari colleghi di seguito l'annuncio di un seminario organizzato nell'ambito delle attività dell'IRL LYSM INdAM-CNRS, a cui siete tutti cordialmente invitati a partecipare. ----------------------------------------------------------- LYSeMinar Martedì 6 maggio, ore 10:30, Sala di Consiglio, Dipartimento di Matematica Guido Castelnuovo, Sapienza Università di Roma, P.le A. Moro 5, 00185 Roma Speaker: Lucia Caramellino (Univ. Roma Tor Vergata) Title: Regularization lemmas and applications Abstract: The talk focuses on some regularization results that allow one to prove estimates in the total variation distance, typically by upgrading already known estimates holding in the Wasserstein distance. In all this, tools from Malliavin calculus will play a crucial role. Some applications will then be discussed. The talk is mainly based on the papers "Regularization lemmas and convergence in total variation", with V. Bally and G. Poly (EJP 2020), and "Convergence in Total Variation for nonlinear functionals of random hyperspherical harmonics", with G. Giorgio and M. Rossi (JFA 2024). -- @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ Domenico Marinucci Dipartimento di Matematica Università di Roma Tor Vergata https://sites.google.com/view/domenicomarinucci @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@

In order to build our numerical scheme, we put forward a new representation of the PDE solution by using a classical probabilistic representation of the gradient. Then, based on this representation, we propose a fully implementable numerical scheme using a Picard iteration procedure, a grid space discretization and a Monte-Carlo approximation. Up to a limiting technical condition that guarantees the contraction of the Picard procedure, we obtain an upper bound for the numerical error. We also provide some numerical experiments that show the efficiency of this approach for small dimensions. -- Gianmario Tessitore Dipartimento di Matematica e Applicazioni Università degli Studi di Milano-Bicocca

Seminars in Statistics at Collegio Carlo Alberto - Marc HOFFMAN (UNIVERSITÉ PARIS-DAUPHINE)
by Matteo Giordano 01 May '25

01 May '25

SEMINARS IN STATISTICS @ COLLEGIO CARLO ALBERTO <https://www.google.com/url?q=https://www.carloalberto.org/events/category/s…> Venerdì 09/05/2025, presso il Collegio Carlo Alberto, in Piazza Arbarello 8, Torino, si terrà il seguente seminario: ------------------------------------------------ 12.00-13.00 Speaker: Marc HOFFMAN (UNIVERSITÉ PARIS-DAUPHINE) Title: some questions in mathematical statistics linked to evolution PDEs Abstract: Evolution models in applications are often analyzed via PDEs, interpreted as a macroscopic description of the phenomenon of interest. This classical approach is nevertheless challenged by empirical data for model validation, especially when the phenomenon of interest does not depend on well established physical laws. In particular the statistical inference of parameters (estimation and testing) requires an underlying stochastic model. This is usually treated via some addition of noise, sometimes artificially and always a bit arbitrarily. Relying on some specific examples that appear in population biology (cell growth, human demography) or agent-based models in economy, we propose an alternative approach. Starting from a microscopic stochastic model that can be partially observed and for which the PDE of interest is a mean-field limit, the intrinsic statistical noise becomes the fluctuation between the empirical measure of the particle system and the solution of the PDE. We will outline a rigorous statistical program in this setting and will give some results on McKean-Vlasov models that shall emphasize the interest of our approach. ------------------------------------------------ Sarà possibile il seminario anche in streaming: chiunque volesse collegarsi è pregato di inviare una email entro *mercoledì 07/05/2025* a matteo.giordano(a)unito.it <mailto:matteo.giordano@unito.it> Il webinar è organizzato dalla "de Castro" Statistics Initiative (www.carloalberto.org/stats <http://www.carloalberto.org/stats>) in collaborazione con il Collegio Carlo Alberto.

QFinLab Seminar - Alessandro Sbuelz (Università Cattolica del Sacro Cuore) - 7/5/2025, 12:15 @ Department of Mathematics, Politecnico di Milano
by Alessandro Calvia 30 Apr '25

30 Apr '25

Dear colleagues, you are all invited to participate in the following seminar organized by QFinLab - Department of Mathematics, Politecnico di Milano. Wednesday, 7 May 2025, 12.15-13.15 Seminar room, third floor, building 14, Via Bonardi 9, Milano (Leonardo Campus) Alessandro Sbuelz (Università Cattolica del Sacro Cuore) Title: The Zero-Theta Hedge Contract. Abstract: We examine long-dated asset valuation under systematic and idiosyncratic risk, driven by extreme trajectories. By introducing the zero-Theta hedge contract, a negative-Delta derivative security with a maturity-independent price, we study investor attitudes toward systematic long-run crashes. Declining expected payoff with maturity signal strong crash aversion. The contract aids in decomposing the stochastic discount factor, shedding light on long-run crash risk premia. Even for volatile assets whose price comes from idiosyncratic rallies, systematic long-run crashes remain central to long-run risk valuation. Based on a joint work with Anna Battauz and Marzia De Donno. Next seminars: Olimpia Carradori (University of Zurich), 5 June 12.00. Marco Tolotti (Università Ca' Foscari Venezia), 9 June 12.15. All news can be found on the QFinLab webpage<https://www.qfinlab.polimi.it/seminars-and-meetings/>. The organizers: Michele Azzone and Alessandro Calvia.

Seminario Padova e Alumni Award - Jacopo Borga
by alekos.cecchin＠unipd.it 30 Apr '25

30 Apr '25

Buongiorno a tutti, Vorremmo segnalarvi che lunedì prossimo (5 Maggio) in aula 1BC45 (Torre Archimede, Università di Padova) ci sarà un seminario per il ciclo di seminari in Probabilità e Finanza di: Jacopo Borga (MIT) <https://www.jacopoborga.com/> https://www.jacopoborga.com Title: Lattice Yang-Mills theory in the large N limit via sums over surfaces Date: May 5, 2025, at 14:30, room 1BC45 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: 1. A rigorous formula in terms of embedded bipartite planar maps of Wilson loop expectations in the large N limit, in any dimension d. 2. 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 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. Segnaliamo inoltre che Jacopo Borga terrà un seminario divulgativo e riceverà l'Alumni Special Award dell’Università di Padova lunedì, 5 maggio in aula 1A150, Torre Archimede Programma: * 16:30.

Crispi 7, L’Aquila) 13/5 (Mon) 14:15-15:45 14/5 (Tue) 16:15-17:45 15/5 (Wed) 10:45-12:15 16/5 (Thu) 10:45-12:15 I will present a complete proof of stochastic quantisation of a family of subcritical (i.e. superrenormalizable) scalar Euclidean QFT via the flow equation method of Duch. Euclidean QFT are measures on distributional fields which should be considered natural generalisation of Markov processes in higher dimension and which play a fundamental role in the rigorous construction of relativistic quantum fields. Stochastic quantisation is a method to realise such measures as pushforward of Gaussian measures via maps obtained by solving PDEs with random sources. In the last 10 years our understanding of the stochastic quantisation method has progressed greatly giving us new methods to attach the problems of EQFTs. The aim of the minicourse is to present, in most of the details, the various aspects of the construction of a particular class of EQFTs showcasing how probabilistic arguments merge with PDE estimates and renormalization group ideas. If the time permits I will also discuss the many open problems and fundamental issues in our understanding of these and more challenging models. ———————————————— Registration is free through the website: https://indico.gssi.it/event/745/. Other courses hosted by the trimester can be found in https://trimester2025.math.gssi.it/all_courses/. We would be grateful if you could circulate the announcement among potentially interested students and researchers.

Mini-courses in GSSI trimester
by Lu Xu 25 Apr '25

25 Apr '25

Dear colleagues and friends, as part of the GSSI intensive trimester “Particles, Fluids and Patterns: analytical and computational challenges”, we are glad to announce 3 short courses in April: April 14-17: Prof. Makiko Sasada (Tokyo) April 28-30: Prof. Oriane Blondel (Lyon) and Prof. Alessandro Giuliani (Rome) Please see at the end of the email for the detailed place and time, titles and abstracts. Other courses hosted by the trimester can be found in https://trimester2025.math.gssi.it/all_courses/. Registration is free through the web form: https://indico.gssi.it/event/745/. We would be grateful if you could circulate the announcement among potentially interested students and researchers. For any information do not hesitate to contact us (patterns(a)gssi.it). ———————————————— Venue for all courses: Main Lecture Hall, Gran Sasso Science Institute (Viale F. Crispi 7, L’Aquila) ———————————————— Introduction to probabilistic aspects of integrable systems Lecturer: Makiko Sasada (The University of Tokyo) 14/4 (Mon) 9:00-10:30 15/4 (Tue) 14:15-15:45 16/4 (Wed) 10:45-12:15 17/4 (Thu) 9:00-10:30 In recent years, there has been growing interest in the study of integrable systems from the perspectives of statistical mechanics and probability theory. The theory of generalized hydrodynamics, developed by mathematical physicists, suggests that the macroscopic behavior of integrable systems is highly universal. To mathematically substantiate such theories with concrete models, a type of cellular automaton called the box-ball system (BBS) has been extensively studied by probabilists in recent years. The BBS, which exhibits solitonic behavior, has been studied from various viewpoints, such as tropical geometry, combinatorics, and representation theory, over 30 years. However, research from the probabilistic perspective began only about 10 years ago. Recently, probabilistic approaches, including the application of the Pitman transform, analysis of invariant measures, and scaling limits, have rapidly expanded. These have revealed new connections between probability theory and classical integrable systems, showing that the macroscopic behavior of integrable systems exhibits a universality distinct from that of chaotic systems. In this lecture, I will introduce these new research topics, mainly focusing on the box-ball system, and present the rigorous results obtained in the past several years, starting from the basic concepts. ———————————————— Long range order in atomistic models for solids Lecturer: Alessandro Giuliani (Rome Tre) 28/4 (Mon) 16:15-17:45 29/4 (Tue) 16:15-17:45 30/4 (Wed) 10:45-12:15 & 14:15-15:45 The emergence of long range order at low temperatures in atomistic systems with continuous symmetry is a fundamental, yet poorly understood phenomenon in physics. To address this challenge I will introduce a discrete microscopic model for an elastic crystal with dislocations in three dimensions, originally proposed by Ariza and Ortiz. The model is rich enough to support some realistic features of three-dimensional dislocation theory, most notably grains and the Read-Shockley law for grain boundaries, which I will review and show how to derive microscopically in the context of the Ariza-Ortiz model, at least in a simple, explicit geometry. I will also explain how to analyze the model at positive temperatures, in terms of a Gibbs distribution with energy function given by the Ariza–Ortiz Hamiltonian plus a contribution from the dislocation cores. The main result is that the model exhibits Long Range Positional Order (LRPO) at low temperatures. Its proof is based on the tools of discrete exterior calculus, together with cluster expansion techniques. In this mini-course I will introduce these methods and explain how to combine them in order to prove existence of LRPO. Time permitting, I will discuss some perspectives about the extension of these ideas and methods to two dimensions. Based on joint work with Florian Theil. ———————————————— Fluctuations in exclusion processes Lecturer: Oriane Blondel (University of Lyon 1) 28/4 (Mon) 10:45-12:15 29/4 (Tue) 9:00-10:30 & 14:15-15:45 30/4 (Wed) 16:15-17:45 We will focus on weakly asymmetric exclusion processes on the line or half-line, and investigate their fluctuations out of equilibrium. We will review the various tools used in proving convergence to the KPZ equation in the strategy initiated in [Bertini-Giacomin ‘97] and discuss how they can be adapted to the singular initial condition that arises when one considers fluctuations of the facilitated exclusion process at the interface. ———————————————— With our best wishes, Lu Xu Assistant Professor (RTDb) Gran Sasso Science Institute
