[STAR Seminars] Wed Feb 25 - Yi Feng
by Leonardo Tarquini 18 Feb '26

18 Feb '26

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 on Wednesday, February 25th, from 11:00 to 12:00 (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/61698784374>. The speaker is Yi Feng (Aarhus University) with the talk: Title: Continuous-Time Analysis of Heavy Ball Momentum in Min-Max Games Abstract: Since Polyak's pioneering work, heavy ball momentum has been widely studied in minimization problems. However, its role in min-max games remains largely unexplored. As a key component of practical min-max algorithms like Adam, this gap limits their eﬀectiveness. In this talk, I will present a continuous-time analysis for heavy ball momentum in min-max games. I will focus on two aspects: convergence to equilibrium and implicit gradient regularization, which describe how momentum shapes the interaction between algorithmic trajectories and the geometry of the min-max loss landscape. We will see that the behavior of heavy ball momentum in min-max games is significantly diﬀerent from that in minimization. Bio: Yi Feng is a Postdoctoral researcher at Aarhus University. His research focuses on understanding the learning dynamics in games and their applications in machine learning. His research is supported by a Danish Data Science Academy Postdoctoral Fellowship. This seminar is jointly organised in collaboration with Trung Tuyen Truong<https://www.mn.uio.no/math/english/people/aca/tuyentt/> from the Several Complex Variables, Logic and Operator algebras group<https://www.mn.uio.no/math/english/?vrtx=unit-view&areacode=151365> at UiO. We are looking forward to seeing you! Best regards, Giulia, Leonardo, Pere, and David

Buongiorno a tutti, Vorremmo segnalarvi che venerdì prossimo (28 Novembre) alle 14:30 in aula 2BC30 (Torre Archimede, Università di Padova) ci sarà un seminario per il ciclo di seminari in Probabilità e Finanza di: Lucio Galeati (Università dell'Aquila) <https://sites.google.com/view/lucio-galeati-math/home> https://sites.google.com/view/lucio-galeati-math/home Title: Anomalous dissipation and anomalous regularization in the Kraichnan model of turbulence Date: November 28, 2025, at 14:30, 2BC30 Abstract: In the 60s Kraichnan proposed a synthetic model for passive scalar turbulence, consisting of a scalar advected by a random Gaussian velocity field, white in time and -Holder continuous in space. Despite its simplicity, this SPDE displays anomalous dissipation of energy, spontaneous stochasticity and intermittency, which are also expected for more realistic turbulent fluids. At the same time, solutions to the inviscid SPDE are unique and can be recovered by vanishing viscosity and mollification schemes. In this talk I will present some recent further understandings on this model: i) solutions to the transport equation with initial data display anomalous regularisation and almost gain Sobolev regularity , but not better; ii) solutions to the continuity equation starting from Dirac deltas instantaneously gain Lebesgue integrability, due to the diffusive behaviour of Lagrangian particle splitting, and their variance at small times grows like . Based on joint works with M. Maurelli, F. Grotto, U. Pappalettera and T. Drivas. Vi aspettiamo numerosi!

SEMINAR: Ester Mariucci @Luiss - 12 feb
by Matteo Iacopini 30 Jan '26

30 Jan '26

Dear all, On Thursday, 12th February, at 12:00 in room A304b, the Department of AI, Data and Decision Sciences of Luiss University of Rome will host a seminar by Ester Mariucci (Université Paris-Saclay) Title: "Understanding the Small Jumps of Lévy Processes: Approximations and Nonparametric Estimation” Abstract: There is a rich literature on approximations of the small jumps of a Lévy process, with a particular focus on Gaussian approximations. These approximations are often used to simplify analysis, but their validity depends critically on the observation scheme, in particular whether the data are collected at high or low frequency. In many situations, the Gaussian approximation may not be appropriate, and a more precise understanding of the law of small jumps is necessary. In this talk, we will discuss two complementary approaches. First, we explore approximations of the small jumps and provide quantitative control of their accuracy using distances such as the Wasserstein distance and total variation. Second, we investigate nonparametric density estimation of the small jumps based on discrete observations of a single trajectory. Estimating this density allows us to better understand the underlying distribution of small jumps. We present results for both low-frequency and high-frequency observation settings. In the low-frequency case, assuming that the Lévy density associated with large jumps is known, a spectral estimator exploiting the deconvolution structure achieves minimax parametric rates of convergence with respect to the integrated L2 loss, up to a logarithmic factor. In the high-frequency case, the assumption on the knowledge of the Lévy measure of large jumps can be relaxed; the rate of convergence then depends on the sampling scheme and on the behavior of the Lévy measure near zero, and is minimax up to a logarithmic factor. We also propose an adaptive penalized procedure to select the cutoff parameter. These results are further extended to include the case where a Brownian component is present. Finally, we illustrate our findings through extensive simulations. Anyone interested in attending is welcome; just email me for logistical purposes. Hoping to meet you there!

Seminar Chiarini at Tor Vergata, February 2
by Michele Salvi 29 Jan '26

29 Jan '26

Dear all, On Monday, February 2nd, at 14h00 in Aula Dal Passo in the Math Department of the University of Rome Tor Vergata, RoMaDS (https://www.mat.uniroma2.it/~rds/events.php) will host Alberto Chiarini (Università di Padova) with the seminar "Fluctuations of the Simple Exclusion Process on Point Processes” Abstract: The simple exclusion process is one of the most prominent models of interacting particle systems. In this seminar, we consider a resistor network whose nodes are sampled according to a simple point process on R^d and are connected by certain conductances. On top of this resistor network, particles move according to random walks with the rule that there is at most one particle per site. Under soft assumptions on the point process measure and conductances, which include ergodicity, stationarity and certain moment conditions, it is known that the empirical density of particles converges for almost all realisation of the environment to the solution of an heat equation with a certain homogenised diffusivity. In this talk, we examine its equilibrium fluctuations. For d≥3, under the same assumptions that ensure the hydrodynamical limit, we show that the empirical density fluctuation field converges for almost all realisation of the environment, in the sense of finite-dimensional distributions, to a generalised Ornstein-Uhlenbeck process. For d=2, if we require some additional regularity on the environment to have Hölder regularity estimates for solutions to parabolic problems, we can show that the same conclusion holds. We encourage in-person partecipation.

Open Ph.D. position at the University of Luxembourg
by Giovanni Peccati 27 Jan '26

27 Jan '26

Dear Colleagues, The *Department of Mathematics* of the *University of Luxembourg* (*DMATH*) is seeking an excellent candidate for a *PhD position* in the area of *Mathematical Statistics*, with an expected starting date in *2026*. *-----------------------* *Supervisor:* Prof. *Yannick Baraud* (https://math.uni.lu/baraud/Home.html) *PhD topic:* *Classical Bayesian methods can be used to construct estimators with good statistical properties. For example, when the data are i.i.d. and come from a distribution belonging to a parameterised model with a suitable prior distribution, numerous studies show that the posterior distribution is concentrated around the parameter associated with the distribution of the data.* *Despite their popularity, these methods nevertheless have certain limitations. In particular, when the data-generating distribution does not belong to the family of distributions chosen as the model, the estimators obtained may be of poor quality, even when the model provides a good approximation of the truth. This situation can arise, for example, when the sample contains a few outliers due to measurement or transcription errors. More generally, it occurs when the statistical model is only a simplification of reality, which is often the case in practice. The statistical method is then said to suffer from a lack of robustness as it produces unstable estimators that are sensitive to small deviations from the assumed model.* *In this PhD proposal, we offer the opportunity to study a robust alternative to classical Bayesian methods. This is a recent approach, the main properties of which were established in [1] in the context of density estimation. The aim of this PhD proposal is to understand the mathematics behind these new techniques and to extend it beyond density estimation. * *A candidate for this position must have a strong background in analysis, probability and mathematical statistics as well as a taste for theory. * [1] Y. Baraud. From robust tests to Bayes-like posterior distributions. Probab.

A well-known result (proved under various assumptions in several references) concerns the convergence in distribution of the network output, in the infinite-width limit, to a centered Gaussian process with i.i.d. components (with the depth $L$ kept fixed). I will present some large deviation results describing a collapse of the network output (which, as expected, converges to the zero vector) when it is multiplied by a scaling factor tending to zero; see [1], where moderate deviations are also studied. In the final part, I will briefly outline some results in a very recent work (see [2]) concerning the deep limit (that is, as $L\to\infty$) for a generic component of the Gaussian process mentioned above.

[STAR Seminars] Wed Jan 21 - Susanna Dehò
by Leonardo Tarquini 21 Jan '26

21 Jan '26

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 on Wednesday, January 21st, from 11:00 to 12:00 (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/67027975721>. The speaker is Susanna Dehò (University of Milano "La Statale") with the talk: Title: Symmetries of SDEs: from invariance properties to integration by parts formulas Abstract: The study of symmetries in differential equations, pioneered by Sophus Lie, constitutes a fundamental geometric approach to understand the invariance properties governing a dynamical system. By identifying the groups of transformations that preserve the equation’s structure, this framework provides systematic tools for order reduction, the construction of exact solutions, and the simplification of complex problems. Although symmetry analysis stands as a classical pillar for deterministic differential equations (ODEs and PDEs), supported by extensive literature, its extension to Stochastic Differential Equations (SDEs) represents a relatively recent field of research. Recent literature has also highlighted significant connections with the symmetries of the associated Fokker-Planck or Kolmogorov equations. Furthermore, the application of Lie symmetry theory to SDEs enables the derivation of integration by parts formulas inspired by Bismut’s variational approach to Malliavin calculus, with notable applications to the analysis of the law and regularity of the processes, as well as to the development of a stochastic calculus of variations. In this talk, we will discuss various notions of symmetry for SDEs, highlighting their connections to established invariance properties of well-known stochastic models and the symmetries of Kolmogorov PDEs. We will analyze how a geometric approach, inspired by Lie’s deterministic framework, enables the development of powerful computational tools for symmetry calculation. Subsequently, we will demonstrate how applying this geometric theory allows for the constructive derivation of an integration by parts formula for SDEs, rooted in Bismut’s approach. Finally, we will show how this integration by parts formula acts as a generating identity for well-known probability formulas, and discuss its connections to Stein’s identities. This contribution is based on a joint work with F.C. De Vecchi, P. Morando and S. Ugolini. Susanna Dehò, Francesco C. De Vecchi, Paola Morando, and Stefania Ugolini. Random rotational invariance of integration by parts formulas within a Bismut-type approach. Journal of Mathematical Physics: in print, 2025. We are looking forward to seeing you!

OWABI - Louis Sharrock - 29th January - 11am UK time
by Massimiliano Tamborrino 20 Jan '26

20 Jan '26

Dear all, the first One World Approximate Bayesian Inference (OWABI) seminar www.warwick.ac.uk/owabi<http://www.warwick.ac.uk/owabi> of the year is quickly approaching! Our next speaker is Louis Sharrock<https://louissharrock.github.io/> <https://louissharrock.github.io/> (University College London) who will talk about "Sequential Neural Score Estimation: Likelihood-free inference with conditional score base diffusion models" on Thursday the 29th January at 11am UK time, with an abstract reported below. The talk will be streamed on the OWABI MS Team channel General | OWABI Seminar: One World Approximate Bayesian Inference Seminar | Microsoft Teams<https://teams.microsoft.com/l/team/19%3AdhZ_4e_XLNJzCXPAMzTvT6BZ5KShEETkd_w…>, at the link below Join: https://teams.microsoft.com/meet/38899039621449?p=nCtiqu8zYnZNL2LGR8 Meeting ID: 388 990 396 214 49 Passcode: f3Dh22XL We are looking forward to seeing you at the next OWABI seminar, Best, Massimiliano on the behalf of the OWABI seminar organisers Speaker: Louis Sharrock (University College London) Title: Sequential Neural Score Estimation: Likelihood-free inference with conditional score base diffusion models Abstract: We introduce Sequential Neural Posterior Score Estimation (SNPSE), a score-based method for Bayesian inference in simulator-based models. Our method, inspired by the remarkable success of score-based methods in generative modelling, leverages conditional score-based diffusion models to generate samples from the posterior distribution of interest. The model is trained using an objective function which directly estimates the score of the posterior. We embed the model into a sequential training procedure, which guides simulations using the current approximation of the posterior at the observation of interest, thereby reducing the simulation cost. We also introduce several alternative sequential approaches, and discuss their relative merits. We then validate our method, as well as its amortised, non-sequential, variant on several numerical examples, demonstrating comparable or superior performance to existing state-of-the-art methods such as Sequential Neural Posterior Estimation (SNPE). Keywords: diffusion models, simulation based inference, sequential methods. Reference: L. Sharrock, J. Simons, S. Liu, M.

Alberto Chiarini e Sonia Mazzucchi %%%%%%%%%%%%%%%%%%%%%%%%%%%% RELATORI: Lorenzo Zambotti e Alberto Bonicelli (Sorbonne Université) TITOLO: La rivoluzione dell’analisi stocastica « pathwise ». RIASSUNTO: L’analisi stocastica, creata da Itô negli anni 40, ha dominato la teoria dei processi stocastici fino alla fine del XX secolo e oltre. Negli ultimi 25 anni una serie di nuove idee ha arricchito questa teoria e permesso dei progressi spettacolari, in particolare nello studio delle equazioni stocastiche alle derivate parziali. Le tecniche principali in questa area di ricerca sono i rough paths, il sewing lemma, le strutture di regolarità e le distribuzioni para-controllate. In questo seminario vogliamo presentare le idee principali di questo settore, in particolare la nozione di integrazione stocastica « pathwise », il teorema di ricostruzione e le espansioni di Taylor generalizzate.

Dear Colleagues, We would like to invite you to the following SPASS seminars, *Some results on the Kraichnan model* by Umberto Pappalettera (Universität Basel) on Tuesday 20.1.2026 at 14:00 CET in Aula Magna, Dipartimento di Matematica, UNIPI. Online participants may join the seminar at https://meet.google.com/ajh-zrxc-wds Best, F. Butori on behalf of the organizers https://sites.google.com/unipi.it/spass ------------------- Abstract: We discuss a number of properties of ``turbulent'' solutions to the Kraichnan model constructed by Le Jan and Raimond in [Ann. Probab. 30(2): 826-873, 2002]. We cover the full range of compressibility ratios giving spontaneous stochasticity of particle trajectories. More specifically, we prove generic anomalous dissipation of the mean energy and fractional Sobolev regularity of solutions, for every square-integrable initial datum. The proof of the latter is obtained as a consequence of a new sharp regularity result for the degenerate parabolic PDE satisfied by the associated two-point self-correlation function, which is of independent interest.

ABS (Applied Bayesian Statistics) school on "Interpretable Bayesian Learning,for Physical and Engineering Sciences" in Como, Italy (July 6-10, 2026)
by Fabrizio Ruggeri 15 Jan '26

15 Jan '26

Dear all, We are glad to inform you that ABS26, the next Applied Bayesian Statistics school, running since 2004, will be held in the city of Como (Italy), along the Lake Como shoreline at the beautiful Villa del Grumello, on July 6-10, 2026. The school is organised by CNR IMATI (Institute of Applied Mathematics and Information Technologies at the Italian National Research Council in Milano), in cooperation with Fondazione Alessandro Volta. The topic will be *Interpretable Bayesian Learning for Physical and Engineering Sciences.* The lecturer will be Prof. *Simon Mak *(Department of Statistical Science, Duke University), a leading expert in integrating domain knowledge (e.g., scientific theories, mechanistic models, guiding principles) as prior information for cost-efficient statistical inference, prediction, and decision-making., with the support of* Yen-Chun Liu* (Department of Statistical Science, Duke University), a brilliant PhD student of Prof. Mak, specializing in Bayesian optimization, Gaussian processes, and reinforcement learning. If interested, you can register on the school website: *https://abs26.imati.cnr.it/* We currently only accept payments by bank transfer, but credit cards will be accepted as soon as possible. As in the past, there will be a combination of theoretical and practical sessions, along with presentations by participants on their work (past, present, and future) related to the school's topic. OUTLINE: This course investigates the rising topic of interpretable statistical learning, motivated by timely needs from modern scientific and engineering applications. For such applications, state-of-the-art machine learning methods often yield analyses that are uninterpretable to scientists, which greatly obfuscates scientific findings and decision-making. Interpretable Bayesian learning provides an elegant and effective solution by embedding scientific principles (e.g., boundary conditions, mechanistic equations) within its prior specification. In this course, we will cover a broad spectrum of interpretable Bayesian learning methods (with theory and algorithms), providing a cohesive roadmap for this recent and rapidly-evolving area of study. This will be complemented by practical case studies from ongoing projects in particle physics, mechanical engineering, and bioengineering. Emphasis will be made on novel directions for research in this promising area. Topics will cover * Fundamentals of Gaussian process (GP) surrogate modeling: prediction, parameter inference, experimental design * Decision-making with GP surrogates: Bayesian optimization, active learning, Bayesian inverse problems * Markov Chain Monte Carlo (MCMC) methods * Boundary-informed GP modeling * Shape-constrained (e.g., monotone, isotonic, convex) GP modeling * Mechanistic GP modeling * Physics-integrated neural networks, its Bayesian variants and recent developments * Dynamical system recovery: SINDy, Bayesian SINDy, and recent developments We hope you will be interested in the school and we would like to meet you in Como. We invite you also to share the information with people potentially interested.

Seminar by H. Vanneuville at Milano-Bicocca (Thu 22 Jan, 11:00, Room U9-05)
by Francesco Caravenna 15 Jan '26

15 Jan '26

I am pleased to announce the following seminar: Hugo Vanneuville (Université Grenoble Alpes) A new proof of exponential decay in percolation Thursday 22 January at 11:00 Room U9-05 (Building U9, Viale dell'Innovazione 10, Milan) An abstract follows below. All interested participants are welcome. Best regards, Francesco Caravenna %%%%%%%%%%%%%%%%%%%%%%%%%% Abstract. Bernoulli percolation of parameter p on Z^d is defined by keeping each edge of Z^d with probability p, independently of the other edges. The exponential decay theorem - proven in 1987 by Menshikov and independently by Aizenman and Barsky - can be stated as follows: If the cardinality of the cluster of 0 is a.s. finite at some parameter p, then it has an exponential moment at every parameter q<p. I like to state this theorem this way because it illustrates the fact that "decreasing p infinitesimally has a regularising effect on the clusters". The goal of this talk is to discuss this theorem and to propose a new proof. Contrary to the other proofs, we do not rely on differential inequalities but rather on stochastic comparisons. %%%%%%%%%%%%%%%%%%%%%%%%%% -- __________________________________ Francesco Caravenna Dipartimento di Matematica e Applicazioni Università degli Studi di Milano-Bicocca https://fcaraven.github.io/ __________________________________

Seminar Stecconi at Tor Vergata, January 19
by Michele Salvi 15 Jan '26

15 Jan '26

Dear all, On Monday, January 19th, at 14h00 in Aula Dal Passo of Tor Vergata Math Department, RoMaDS (https://www.mat.uniroma2.it/~rds/events.php) will host Michele Stecconi (University of Luxembourg) with the seminar "Universal cancellations in Uniform Random Waves” Abstract: I will present the model of "Uniform Random Waves", obtained by dividing a Gaussian random wave by its L2-norm, on the sphere and other Riemannian manifolds. This choice has deep motivations, although the Gaussian case predominates in the existing literature. I will compare the analysis of these two classes of random fields, focusing on (Wiener) chaos decomposition of geometric functionals and on new surprising (Berry) cancellation phenomena that arise in the uniform setting. Based on the homonymous paper, with L. Gass, D. Marinucci, G. Peccati, F. Pistolato. We encourage in-person partecipation.

SPASS seminar: Ivan Kryven - Fri 23 Jan at 10.00
by Elia Bisi 14 Jan '26

14 Jan '26

Dear Colleagues, We would like to invite you to the following SPASS seminar (joint organised by UniPi, SNS, UniFi and UniSi): A Limit Theorem for the Total Progeny Distribution of Multitype Branching Processes by Ivan Kryven (Utrecht University). The seminar will take place in person on Friday 23rd January at 10:00 in Aula Tricerri, Department of Mathematics and Computer Science, University of Florence. It will be also streamed online here: https://meet.google.com/boc-aphg-bbk On behalf of the organisers, Elia Bisi ------------------- Abstract: Multitype branching processes model random trees whose vertices carry types, with each vertex producing offspring according to a type‑dependent multivariate distribution. In this talk, I will present a limit theorem describing the behavior of such processes in the noncritical regime. Specifically, we show that the relative frequencies of the different types in any finite realization converge to a deterministic vector, and that the distribution of the total progeny exhibits exponential decay. These results require only that all moments of the offspring distribution exist. The proof combines several analytic tools, including the Lagrange–Good and arborescent Lagrange inversion formulas, a measure‑tilting argument, and a local limit theorem. I will also discuss applications to models such as random graphs and multi‑component coagulation processes. Joint work with Jochem Hoogendijk and Rik Versendaal. ————————— Elia Bisi Assistant Professor (RTT) University of Florence Department of Mathematics & Computer Science Personal homepage Florence Probability group

Dr. Anna Gallo's seminar at University of Milano-Bicocca.
by Giorgio Rizzini 14 Jan '26

14 Jan '26

Dear all, we are pleased to announce the following seminar by Dr. Anna Gallo (IMT School for Advanced Studies Lucca) on *Thursday, January 15th 2026,* starting at 11:00 in room 4057, the Department of Statistics and Quantitative Methods, University of Milano-Bicocca (Milan): *Rethinking balance theory: a probabilistic approach to the study of signed networks* *Abstract:* Networks provide a powerful language to model interacting systems by representing their units as nodes and the interactions between them as links. Interactions can be connotated in several ways, such as binary/weighted, undirected/directed, etc. In the present talk we focus on the positive/negative connotation- modelling trust/distrust, alliance/enmity, friendship/conflict, etc. - by considering the so-called signed networks. Rooted in balance theory, a psychological framework that has been proposed to model human relationships, the study of signed networks has found application in fields as different as biology, ecology, economics. Here we approach it from the perspective of statistical physics, by extending the framework of Exponential Random Graph Models to the class of binary, un/directed, signed networks and employing it to assess the significance of frustrated patterns in biological, economic and social networks. The degree of balance critically depends on i) the considered system and ii) the employed benchmark: while social networks align with balance theory - with heterogeneous null models supporting its strong version and homogeneous null models supporting its weak version, biological networks often exhibit a pronounced level of frustration. For what concerns binary, directed networks, instead, we explore the relationship between frustration and reciprocity and suggest an alternative interpretation of balance in the light of directionality. Finally, we investigate signed structures at the mesoscopic scale by evaluating the tendency of a configuration to be either `traditionally' or `relaxedly' balanced.

[STAR Seminars] Wed Jan 14 - Rahma Yasmina Moulay Hachemi
by Leonardo Tarquini 13 Jan '26

13 Jan '26

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 on Wednesday, January 14th, from 11:00 to 12:00 (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/67027975721>. The speaker is Rahma Yasmina Moulay Hachemi (University of Saida Dr. Moulay Tahar) with the talk: Title: The stochastic heat inclusion with fractional time derivative driven by time-space Brownian white noise Abstract: We study a time-fractional stochastic heat inclusion driven by additive time-space Brownian noise given by: ∂^α/∂t^α Y (t, x) ∈ λ∆Y (t, x) + G(t, x, Y (t, x)) + σW (t, x); (t, x) ∈ (0, ∞) × R^d. Here d ∈ N = {1, 2, ...} is the space dimension, x ∈ R^d denotes a point in space, t ≥ 0 denotes the time. Here d ∈ N = {1, 2, ...} is the space dimension, x ∈ R^d denotes a point in space, t ≥ 0 denotes the time. The fractional time derivative is interpreted as the Caputo derivative of order α ∈ (0, 2). We show the following: a) If a solution exists, then it is a fixed point of a specific set-valued map. b) Conversely, any fixed point of this map is a solution of the heat inclusion. We are looking forward to seeing you! Best regards, Giulia, Leonardo and Pere

SPASS seminar: Pierfrancesco Beneventano
by Marco Romito 09 Jan '26

09 Jan '26

Dear Colleagues, We would like to invite you to the following SPASS seminars, *Edge of Stochastic Stability: SGD does not train neural networks as you expect it* by Pierfrancesco Beneventano (MIT) on Tuesday 13.1.2026 at 14:00 CET in Saletta Riunioni, Dipartimento di Matematica, UNIPI. A link for online participants will be shared on the website https://sites.google.com/unipi.it/spass Best, M. Romito on behalf of the organizers ------------------- Abstract: Recent findings demonstrate that when training neural networks using full-batch (deterministic) gradient descent with step size η, the largest eigenvalue λ of the Hessian consistently stabilizes around 2/η. These results are surprising and carry significant implications for convergence and generalization. This, however, is not the case for mini-batch optimization algorithms, limiting the broader applicability of the consequences of these findings. We show that mini-batch Stochastic Gradient Descent (SGD) trains in a different regime, which we term Edge of Stochastic Stability (EoSS). In this regime, what stabilizes at 2/η is Batch Sharpness: the expected directional curvature of mini-batch Hessians along their corresponding stochastic gradients. As a consequence, λ---which is generally smaller than Batch Sharpness---is suppressed, aligning with the long-standing empirical observation that smaller batches and larger step sizes favor flatter minima. We further discuss implications for mathematical modeling of SGD trajectories.

Seminari Filippo De Feo e Mattia Martini - Politecnico di Milano - 8 Gennaio 2026
by Luca Scarpa 07 Jan '26

07 Jan '26

Si ricordano i seguenti 2 seminari a tutti gli interessati. SEMINARIO 1: Giovedì 8 Gennaio 2026, ore 11:00. Aula Seminari III Piano, Dipartimento di Matematica, Politecnico di Milano. Speaker: Filippo De Feo, Technische Universität Berlin. Title: Stochastic Optimal Control of Interacting Particle Systems in Hilbert Spaces and Applications in Economics. Abstract: Optimal control of interacting particles governed by stochastic evolution equations in Hilbert spaces is an open area of research. Such systems naturally arise in formulations where each particle is modeled by stochastic partial differential equations, path-dependent stochastic differential equations (such as stochastic delay differential equations or stochastic Volterra integral equations), or partially observed stochastic systems. In this talk we present a limiting theory as the number of particles tends to infinity. We apply the developed theory to problems arising in economics where the particles are modeled by stochastic partial differential equations and stochastic delay differential equations. The talks is based on [F. de Feo, F. Gozzi, A. Swiech, L. Wessels, Stochastic Optimal Control of Interacting Particle Systems in Hilbert Spaces and Applications, arXiv preprint arXiv:2511.21646] Link Zoom: https://polimi-it.zoom.us/j/92373976166?pwd=pvQAMGRkAnZ6WLaEXawDkGmbxa61VV.1 Link Seminario Polimi: https://www.mate.polimi.it/eventi/?id=2663&sezione_di_ricerca=probstat&stri… SEMINARIO 2: Giovedì 8 Gennaio 2026, ore 11:45. Aula Seminari III Piano, Dipartimento di Matematica, Politecnico di Milano. Speaker: Mattia Martini, École polytechnique, Centre de Mathématiques Appliquées, Palaiseau. Title: Regularisation in mean field models via infinite dimensional diffusion. Abstract: This talk aims to show how randomizing the dynamics in mean field models can help regularize the associated partial differential equations on the space of probability measures. A key challenge in this approach lies in constructing a suitable notion of noise on the space of probability measures. To this end, we rely on the Dirichlet–Ferguson diffusion process, as studied by Dello Schiavo [AOP 22]. We first examine the effect of this noise on a system of uncontrolled interacting particles and show that it induces a regularizing effect at the level of the corresponding backward Kolmogorov equation. We then analyze a mean field control problem driven by this noise and prove that the associated Hamilton–Jacobi equation admits a unique solution in an appropriate functional space, even when the coefficients have limited regularity. The talk is based on a joint work with F. Delarue (Nice) and G. Sodini (Vienna).

seminario Felix Liebrich in Bicocca
by Fabio Bellini 07 Jan '26

07 Jan '26

Il giorno lunedì 12 gennaio alle ore 17 presso la aula seminari 4096 al quarto piano dell'edificio U7 della Università di Milano-Bicocca, il dott. Felix-Benedikt Liebrich della Università di Amsterdam terrà un seminario dal titolo Lambda-quantiles: A closer look at the new kid on the block Abstract: Lambda-VaR has initially been suggested by Frittelli et al. (2014) as a generalisation of classical Value-at-Risk. Recent years have seen a surge in work on these functionals (or slightly more generally: on Lambda-quantiles), both in financial and insurance applications and from a decision-theoretic perspective. This talk focuses on Lambda-quantiles of univariate probability distributions which generalise classical quantiles by replacing the defining constant threshold in the unit interval with a function Lambda mapping the real line to the unit interval. Working under minimal assumptions, we analyse how the choice of Lambda determines mathematical properties of the resulting functional. In particular, we examine aggregation behaviour, continuity, identifiability of the functional parameter Lambda, and the preservation of finer properties of classical quantiles such as ordinal covariance. We conclude by discussing interpretational issues in financial applications. Based on joint work with Fabio Bellini. Tutti gli interessati sono invitati a partecipare.
