Since its introduction in the 1980s, it has been extensively studied by mathematicians and physicists alike, and its profound impact was recognized with the 2024 Nobel Prize in Physics awarded to John J. Hopfield. In the first part of this talk, I will review its key properties from a mathematical standpoint, focusing on foundational aspects such as the proof of the existence of the thermodynamic limit for the model’s free energy. In the second part, I will explore several extensions and variations of the *model that address contemporary challenges, including AI sustainability and the issue of model collapse. A presto!

Avviso di seminario - Prof. Kei Kobayashi
by luigia.caputo 04 Nov '25

04 Nov '25

Il giorno 10 novembre 2025, alle ore 15:00, in SP1L, del Dipartimento di Matematica e Applicazioni R. Caccioppoli, il Prof. Kei Kobayashi, Department of Mathematics, Fordham University, terrà il seguente seminario: "Eﬀect of random time changes on Loewner hulls" Abstract: Standard Brownian motion composed with a random time change given by an inverse subordinator has been used to model subdiﬀusions, where particles spread more slowly than the classical Brownian particles. The time-changed Brownian motion is neither Markovian nor Gaussian, and standard procedures known for normal diﬀusions do not generally work. This talk gives an overview of the framework of numerical approximation schemes for the time-changed Brownian motion and its associated stochastic diﬀerential equations, along with the rates of convergence. This is based on joint work with Sixian Jin and Ernest Jum. Sarà possibile seguire il seminario anche on line all'indirizzo: Seminario Prof. Kei Kobayashi | Partecipazione alla riunione | Microsoft Teams [1] Cari saluti, Luigia Caputo -- Luigia Caputo, PhD Ricercatore Universitario di Probabilità e Statistica Matematica, Dipartimento di Matematica e Applicazioni, Università di Napoli FEDERICO II Via Cintia, 80126, NAPOLI https://www.docenti.unina.it/luigia.caputo Links: ------ [1] https://teams.microsoft.com/meet/3820570043887?p=SREudpw04NV0e4hOLU

[STAR Seminars] Tuesday Nov 11 - Paul Ehling
by Leonardo Tarquini 03 Nov '25

03 Nov '25

Dear all, Join us for our upcoming talk in the STAR seminar<https://www.mn.uio.no/math/english/research/projects/storm/events/seminars/…> series Tuesday, November 11th, from 13:00 to 14:00 (Oslo time). As always, the talk will take place in a hybrid format: participants in Oslo can attend the talk in Room 723 in Niels Henrik Abels hus, whereas the international audience will be able to follow the talk via Zoom<https://uio.zoom.us/j/62796699609>. The speaker is Paul Ehling (BI Norwegian Business School) with the talk: Title: Asset pricing implications of default Abstract: Studying the asset pricing implications of default, we show that default along the equilibrium path reduces the amount of risk-sharing for two reasons. First, the potential of future default events for relatively poor agents increases their cost of borrowing today. Second, the option value of default in the future induces increased borrowing today, even for relatively rich agents. We establish that agents borrow from each other simultaneously in equilibrium and that they borrow more when idiosyncratic risk is high. Further, we show that this increases the probability of default along the equilibrium path which drives up the premium on risky assets. To solve our dynamic model example with multiple agents numerically, we rely on a machine learning framework to overcome the large state space and the non-linearities due to default. We are looking forward to seeing you! Best regards, Giulia, Leonardo and Pere

Seminario on-line PRISMA lunedì 3 novembre 2025 - L. Benigni & G. Cipolloni
by Sonia Mazzucchi 03 Nov '25

03 Nov '25

Seminari on-line del gruppo UMI - PRISMA (http://www.umi-prisma.polito.it/) 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. Dallo scorso anno le registrazioni dei seminari vengono pubblicate sul canale YouTube dell'UMI: https://youtube.com/playlist?list=PLmySpc-jrtAMq84VH71evyqPc1hl6eEQb Il prossimo appuntamento è per oggi *lunedì 3 novembre* 2025. I relatori saranno *Lucas Benigni *(Università di Montreal) e *Giorgio Cipolloni* (Università di Roma 2 Tor Vergata) che parleranno di: *The mystery of universality in Random Matrix Theory*. 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/88089787189 ID riunione: 880 8978 7189 Codice d’accesso: 144017 Vi aspettiamo numerosi! Alberto Chiarini e Sonia Mazzucchi %%%%%%%%%%%%%%%%%%%%%%%%%%%% RELATORI: Lucas Benigni (Università di Montreal) e Giorgio Cipolloni (Università di Roma 2 Tor Vergata) TITOLO: The mystery of universality in Random Matrix Theory. RIASSUNTO: Over the past fifteen years, our understanding of universality in random matrix theory has undergone a remarkable transformation. For many models of large random matrices, it is now known that both eigenvalue statistics and eigenvector structures exhibit universal behavior that depends only on the symmetry class and not on the fine details of the matrix entries. This universality lies at the heart of deep conjectures in mathematical physics—connecting topics as diverse as quantum chaos, number theory, and high-dimensional statistics—and has become one of the major success stories of modern probability theory. In this two-part colloquium, we will survey these advances with a focus on Wigner matrices, Hermitian or symmetric random matrices with i.i.d. entries up to the symmetry constraint. The first part will discuss universality of eigenvalues, from local spectral laws to modern proofs of universality of local statistics. The second part will turn to eigenvectors, highlighting recent progress on delocalization, quantum ergodicity, and eigenvector statistics.

New COST Action on Stochastic Differential Equations
by Alessandro Ramponi 31 Oct '25

31 Oct '25

Dear Colleagues, We are pleased to announce the launch of a new COST Action devoted to advancing research and collaboration in the broad field of Stochastic Differential Equations (SDEs) and their applications across probability, statistics, and related disciplines. This Action brings together researchers from across Europe and beyond who are working on the mathematical, computational, and applied aspects of stochastic dynamics. It aims to create an interdisciplinary network connecting experts in probability theory, mathematical statistics, stochastic analysis, and applied modeling. The Action supports scientific networking by organising workshops, training schools, seminars, and supporting short-term scientific missions by its members to other countries. Our scientific work is organized around five Working Groups: 1. WG1: Theory of SDEs 2. WG2: Numerical and Computational Methods 3. WG3: Inference and Statistics for SDEs 4. WG4: Applications and Modeling 5. WG5: Education, Dissemination, and Networking We invite researchers and students interested in any of these areas to participate in the Action’s activities — workshops, training schools, and collaborative projects. Participation is open to scientists from all COST member countries. For further information and to join a Working Group, please visit https://www.cost.eu/actions/CA24104/ Best regards, Alessandro Ramponi (COST Action Management Committee)
