Seminario Padova - Vanessa Jacquier
by Alberto Chiarini 28 May '25

28 May '25

Buongiorno a tutti, Vorremmo segnalarvi che venerdì prossimo (30 Maggio) alle ore 14:30 in aula 2AB30 (Torre Archimede, Università di Padova) ci sarà un seminario per il ciclo di seminari in Probabilità e Finanza di: Vanessa Jacquier (Università di Padova) Title: Discrete Nonlocal Isoperimetric Inequality and Analysis of the Long-Range Bi-Axial Ising Model Date: May 30, 2025, at 14:30, 2BC30 Abstract: We consider a generalization of the classical perimeter, referred to as the nonlocal bi-axial discrete perimeter, in which not only the external boundary of a polyomino contributes to the perimeter, but all its internal and external components. In particular, this nonlocal bi-axial perimeter is a fractional function that depends on the shape of the given geometrical figure and on a parameter λ>1, which accounts for the long-range effect. We tackle the nonlocal discrete isoperimetric problem analyzing and characterizing the minimizers within the class of polyominoes with a fixed area. The solution of this isoperimetric problem provides a rigorous foundation for studying the metastable behavior of the long-range bi-axial Ising model. Vi aspettiamo numerosi!

Seminario di Amichai Painsky presso l'università Bicocca, Mercoledì 4 giugno
by Mario Beraha 27 May '25

27 May '25

Buongiorno a tutti, Vi segnalo il seguente seminario in presenza presso l’università di Milano-Bicocca. 4 giugno 2025, ore 12:00, Aula Seminario 2104, Edificio U7, Via Bicocca degli Arcimboldi, 8, Milano. Speaker: Amichai Painsky, Tel Aviv University Title: Large Alphabet Inference Abstract: Consider a finite sample from an unknown distribution over a large alphabet. Making inference in a large alphabet regime is a fundamental problem in statistics and related fields, which entails several basic challenges. For example, how accurately can we infer the parameters of events that do not appear in the sample? What can we say about the most frequent events in the sample? The entire underlying distribution? In this talk we introduce a novel inference scheme that tackles these challenging problems. Our proposed framework applies selective inference, as we construct confidence intervals (CIs) for the desired set of parameters. Interestingly, we show that obtained CIs are dimension-free, as they do not grow with the alphabet size. Further, we show that our CIs are (almost) tight, in the sense that they cannot be further improved without violating the prescribed coverage rate.

Short courses in GSSI trimester
by Lu Xu 27 May '25

27 May '25

Dear colleagues and friends, we are glad to announce the forthcoming short courses and seminar in GSSI in June: June 3-5 (short cours) & June 6 (seminar): Prof. Gian Michele Graf (ETH Zurich) June 10-12: Prof. Lenya Ryzhik (Stanford) Please see at the end of the email for the detailed information. Registration is free through the web form: https://indico.gssi.it/event/745/. Other courses hosted by the trimester can be found here: https://trimester2025.math.gssi.it/all_courses/. 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<mailto:patterns@gssi.it>). ———————————————— Venue: Main Lecture Hall, Gran Sasso Science Institute (Viale F. Crispi 7, L’Aquila) ———————————————— Matter and topology: an overview Gian Michele Graf (ETH Zurich) 3/6 (Tue) 14:15-15:45 5/6 (Thu) 14:15-15:45 6/6 (Fri) 09:00-10:45 Topological insulators are materials that are conducting at their edge, though not in the bulk. Their essential physical properties are encoded by an index. After reviewing the historical origins, and the Quantum Hall effect in particular, the appropriate indices will be discussed (Chern numbers, index of a pair of projections), as well as bulk-edge correspondence. Thereafter symmetry protected topological insulators will be addressed. The focus will be on symmetries like time-reversal and particle-hole conjugation and, correspondingly, on the Quantum Spin Hall effect and Majorana zero modes in superconductors, in physical dimensions d=2 and 1, respectively. More broadly, the Kitaev table describes the kind of indices that occur in relation to many more symmetries, in any dimension d, and its derivation will be treated. Special topics beyond the above framework, such as time-dependent systems (Floquet or quantum pumps) or classical systems (hydrodynamics) may occur too, as time permits. ———————————————— SMAQ Seminar: Adiabatic charge pumps and Galilei covariance Gian Michele Graf (ETH Zurich) 6/6 (Fri) 14:00-15:30 The Thouless theory of quantum pumps establishes quantized transport per cycle and determines the necessary conditions. When the description is shifted to a moving reference frame, as suggested by recent experiments on ultracold gases, transported and residing charges mix. That transformation is encoded in Galilean space and time, but underlying it is one of vector bundles that may be described in a number of ways, that may or may not rely on Bloch theory. In one of them, the transformation mixes strong and weak indices of a bundle on a 2-torus; in another one, a 3-torus is at center stage; in yet another one, and somewhat informal way, the transformation is related to a paradox that astonished seafarers of centuries past. Joint work with T. Esslinger and F. Santi. ———————————————— Branching Brownian motion and knowledge diffusion: from Fisher-KPP to MFG Lenya Ryzhik (Stanford) 10/6 (Tue) 16:15-17:45 11/6 (Wed) 10:45-12:15 & 16:15-17:45 12/6 (Thu) 16:15-17:45 We will first discuss the general connection, via the voting models, between the branching Brownian motion (BBM) and the Fisher-KPP and other semilinear parabolic equations. This connection, together with the long time asymptotics of the solutions, allows, in particular, to deduce some fine properties of BBM, such as the law of large numbers and fluctuations of the limiting process near the maximum of BBM. In the second half of the lectures, we will discuss some knowledge diffusion models that arise in macroeconomics and lead to mean-field game type of problems that are also related to non-local Fisher-KPP equations. ———————————————— With our best wishes, Lu Xu Assistant Professor (RTDb) Gran Sasso Science Institute

Seminario di Hakima Bessaih - Pavia, 3 giugno 2025 ore 14
by Benedetta Ferrario 27 May '25

27 May '25

Martedì *3 giugno alle ore 14* presso il Dipartimento di Scienze Economiche e Aziendali (aula E, piano terra) dell'Università di Pavia, la prof.ssa Hakima Bessaih terrà un seminario: *titolo*: Dynamical systems with noisy data *abstract*: Reconstructing the state of a dynamical system from noisy observations is particularly challenging when the initial conditions are unknown. This talk focuses on synchronization-based and feedback control methods for data assimilation, which dynamically align model trajectories with observed data. Techniques such as nudging, observer-based schemes, and coupling strategies will be discussed, highlighting how they correct for uncertainty and stabilize the system in real time. Applications include chaotic systems and models governed by stochastic dynamics. Tutti gli interessati sono invitati a partecipare. Un cordiale saluto Benedetta Ferrario
