Seminars Sapienza University: L. Cristofaro, W. Bock - 27-11-2025
by Luisa Beghin 21 Nov '25

21 Nov '25

Dear all, on* Thursday 27th November* the following seminars will be held at the *Department of Statistical Sciences, Sapienza University*: *Time: 14:30* *Speaker: Lorenzo Cristofaro (University of Luxembourg)* *Title: *A novel p-Poincaré inequality and a multiplication formula *Abstract:* We show a novel family of p-Poincaré inequalities for almost surely finite random variables (p ∈ [1, 2]). Regarding the case of multiple Wiener-Ito integrals, our results yield general multiplication formulae on the Poisson space under minimal conditions, naturally expressed in terms of diagrams and/or contraction operators. *Time: 15:15* *Speaker: Wolfgang Bock (Linnaeus University, Vaxjo, Sweden)* *Title: *The characterization of Malliavin-Watababe-Sobolev spaces via the Bargmann-Segal Space *Abstract: *The characterization theorem and its corollaries set the foundation of the success of white noise analysis in the recent 30 years. On different occasions the fathers of the characterization J. Potthoff and L. Streit were asked by P. Malliavin and P.-A. Meyer if such a characterization is also possible for the Mallliavin-Watanabe Sobolev spaces. In this talk we present how we closed this gap and give a characterization of the Mallliavin-Watanabe Sobolev spaces with the help of the Bargmann-Segal transform. The characterization can also be generalized to the non-Gaussian setting. Examples will showcase the regularity of different objects.

SPASS seminars: E. Tassi and J. Coe
by Francesco Grotto 20 Nov '25

20 Nov '25

Dear Colleagues, We would like to invite you to the following SPASS seminars, *Hamiltonian fluid models for plasmas in the presence of a strong guide field* by Emanuele Tassi (Observatoire de la Côte d'Azur), and *Transition densities for the 2d stochastic Navier-Stokes equations* by James Coe (University of Edinburgh), to be held consecutively on TUE 25.11.2025 at 14:00 and 15:00 CET in Sala Riunioni, Dipartimento di Matematica, UNIPI. A link for online participants will be shared on the website https://sites.google.com/unipi.it/spass Best, Francesco Grotto on behalf of the organizers ---------------------------------------------------------------- /Abstract (Tassi): Fluid models provide an effective tool for describing the dynamics of ionized gases such as plasmas. In particular, in some laboratory and astrophysical contexts (for instance, tokamak devices for thermonuclear fusion, or the solar wind) the dynamics of a plasma can be effectively described by means of fluid models assuming the presence of a dominant, constant in time, component of the magnetic field (strong guide field assumption). Several models of this kind have been derived and used for studying phenomena such as turbulence and magnetic reconnection. In the two-dimensional, non-dissipative limit, many of these models were shown to possess a reformulation in terms of advection equations for Lagrangian invariants. A paradigmatic example of this family of models consists of the two-field model derived by Schep, Pegoraro and Kuvshinov (Phys. Plasmas 1, 2843 (1994)). The formulation in terms of Lagrangian invariants is concomitant with the noncanonical Hamiltonian structure of these models.In this talk, I will show how the possibility of this reformulation and the existence of the corresponding noncanonical Hamiltonian structure can be traced back to the common origin of these models from a parent kinetic model of the so-called gyrokinetic, or drift-kinetic kind.With this approach, new Hamiltonian fluid models can also be derived, describing the evolution of an arbitrary number of Lagrangian invariants in two dimensions. Some general properties of models that can be derived by means of this approach will also be discussed. / /Abstract (Coe): We consider a family of 2d incompressible Navier-Stokes equations with Gaussian forcing that is white-in-time and coloured-in-space. We show that the laws of solutions at any given time are equivalent to those of the corresponding Ornstein-Uhlenbeck process, and in particular the invariant measures are equivalent.We establish a nonlinear version of the "time-shifted Girsanov method" of [Mattingly-Suidan, Mattingly-Romito-Su], enabling a direct comparison between the laws of nonlinear dissipative SPDEs. Then, exploiting the skew-symmetric structure of the Navier-Stokes nonlinearity, we construct a modified system that leaves the Gaussian measure invariant while remaining comparable to the Navier-Stokes dynamics. This talk is based on joint work with Martin Hairer and Leonardo Tolomeo. /

Seminar Andreis at Tor Vergata, November 24
by Michele Salvi 19 Nov '25

19 Nov '25

Dear all, On Monday, November 24th, at 14h00 in Aula Dal Passo of Tor Vergata Math Department, RoMaDS (https://www.mat.uniroma2.it/~rds/events.php) will host Luisa Andreis (Università degli studi di Torino) with the seminar "Large deviations for the covariance process in fully connected Gaussian neural networks” Abstract: In this talk, we study fully connected Gaussian deep neural networks, focusing on their covariance process. In particular, we establish a large deviation principle (LDP) for this process in a functional framework, viewing it as a trajectory in the space of continuous functions. As key applications of our main results, we derive posterior LDPs under Gaussian likelihoods in both the infinite-width and mean-field regimes. We will outline the main ideas of the proof, emphasizing that it relies on an LDP for the covariance process regarded as a Markov process taking values in the space of non-negative, symmetric, trace-class operators equipped with the trace norm. This talk is based on joint work with F. Bassetti and C. Hirsch. We encourage in-person partecipation.

Seminario Padova - Simone Baldassarri

17 Nov '25

Buongiorno a tutti, Vorremmo segnalarvi che venerdì prossimo (3 Ottobre) in aula 2AB40 (Torre Archimede, Università di Padova) ci sarà un seminario per il ciclo di seminari in Probabilità e Finanza di: Simone Baldassarri (Gran Sasso Science Institute (GSSI)) <https://sites.google.com/view/simonebaldassarri> https://sites.google.com/view/simonebaldassarri Title: How opinions evolve on dense dynamic random graphs Date: October 3, 2025, at 14:30, 2AB40 Abstract: Describing the evolution of dynamic networks together with dynamic processes running on them constitutes a major challenge in network science. Despite considerable efforts in past years, and notable progress on an intuitive and approximative level, our mathematical understanding of such systems is still in its infancy. The focus of this talk will be two-opinion voter models on dense dynamic random graphs. The goal is to understand and describe the occurrence of consensus versus polarisation over long periods of time. The former means that all vertices have the same opinion, the latter means that the vertices split into two communities with different opinions and few disagreeing edges. We consider three models for the joint dynamics of opinions and graphs: one with one-way feedback and two with two-way feedback. Key results cover functional laws of large numbers for the densities of the two opinions, functional laws of large numbers for the dynamic random graphs in the space of graphons, and a characterisation of the limiting densities in terms of Beta-distributions. This talk is based on a joint work with P. Braunsteins, F. den Hollander and Michel Mandjes. Vi aspettiamo numerosi!

REMINDER: [STAR Seminars] Tuesday Nov 18 - Ihsan Arharas
by Leonardo Tarquini 17 Nov '25

17 Nov '25

Dear all, This is a gentle reminder about this week's STAR seminar scheduled for tomorrow, November 18th, 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 Møterom 1000 in Niels Henrik Abels hus, whereas the international audience will be able to follow the talk via Zoom<https://uio.zoom.us/j/65363110080>. The speaker is Ihsan Arharas (Linnaeus University) with the talk: Title: American options under asymmetric information in the predictable setting Abstract: We study the valuation of American contingent claims with irregular payoff processes in a financial market where the buyer possesses additional information. The seller operates with respect to the public filtration, while the buyer acts under an initially enlarged filtration. In this setting, we investigate the value of the American contingent claim when the buyer exercises the option according to predictable stopping strategies, i.e. exercise rules that can be announced in advance. This formulation is particularly relevant in the absence of regularity, since enlargement may transform jump times that are totally inaccessible under the public filtration into predictable times under the enlarged one. Within this framework, the value of the American contingent claim is characterized through the solution of a reflected backward stochastic differential equation (RBSDE) in the predictable setting, and the difference between the two information structures provides a representation of the cost of the additional information. We are looking forward to seeing you! Best regards, Giulia, Leonardo and Pere

Seminario Maurice Duits Sapienza
by Gustavo Posta 17 Nov '25

17 Nov '25

Dear all, On Monday November 24, Maurice Duits (http://www.math.kth.se/~duits) will give a seminar at the Department of Mathematics "Guido Castelnuovo" (Sapienza Università di Roma). Please find the details below. GP ************************************************ Monday November 24 2025 16:15, Sala Consiglio del Dipartimento di Matematica "Guido Castelnuovo" Sapienza Università di Roma Speaker: Maurice Duits Title: The Gamma disordered Aztec diamond Abstract: The Aztec diamond, under the uniform measure on domino tilings, is one of the classic examples of an exactly solvable model in probability and statistical mechanics. Its rich geometric features—such as limit shapes and arctic boundaries—have long made it a cornerstone of integrable probability. More recently, variants of this model with doubly periodic weights have revealed that much of the underlying structure persists far beyond the uniform case and can be used to uncover new behaviors—such as regions with smooth disorder—that were previously out of reach. At the heart of these models lies a birational map that encodes their integrable character. In this talk, I will present a new disordered version of the Aztec diamond obtained by placing Gamma-distributed weights on its edges. Remarkably, these random weights preserve just enough structure to keep the model integrable, This allows us to provide rigorous confirmation of predictions from the physics literature—such as the absence of a phase transition in the free energy—and explain the emergence of n^2/3 fluctuations near the turning points. Remarkably, these turning points are related to certain integrable polymer models. The presentation is aimed at a broad mathematical audience and is based on on joint work with Roger van Peski. ************************************************ ---------------------------------------------------------------- Gustavo Posta Dipartimento di Matematica Università di Roma "la Sapienza" P.le A.

Seminario on-line PRISMA lunedì 1 dicembre 2025 - Ilya Chevyrev & Hao Shen
by Sonia Mazzucchi 17 Nov '25

17 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 *lunedì 1 dicembre* 2025. I relatori saranno *Ilya Chevyrev* (Sissa - Trieste) e *Hao Shen* (University of Wisconsin-Madison) che parleranno di: *Stochastic quantisation of gauge theories* *.* 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/84292750177 ID riunione: 842 9275 0177 Codice d’accesso: 549245 Vi aspettiamo numerosi! Alberto Chiarini e Sonia Mazzucchi %%%%%%%%%%%%%%%%%%%%%%%%%%%% RELATORI: Ilya Chevyrev (Sissa - Trieste) e Hao Shen (University of Wisconsin-Madison) TITOLO: Stochastic quantisation of gauge theories RIASSUNTO: We will give an introduction to gauge theories, especially Yang-Mills theory, from a probabilistic perspective. Gauge theories arise in physics, where they are used to describe elementary particles, and correspondingly provide many rich problems in mathematics, including in probability and analysis. We will survey recent results on the interaction between quantum Yang-Mills theory and stochastic analysis, especially the field of singular stochastic PDEs. We will describe how the stochastic quantisation equations associated to the 2D and 3D Euclidean Yang-Mills theories can be solved in a geometrically faithful way and what these equations can teach us about the quantum field theory.

SPASS Seminar: Matteo Palmieri
by Francesco Grotto 16 Nov '25

16 Nov '25

Dear Colleagues, We would like to invite you to the following SPASS seminar, *On minimizing curves in a Brownian potential* by Matteo Palmieri (Max Planck Inst. Lepzig), WED 19.11.2025 at 14:00 CET in Saletta Riunioni, Dipartimento di Matematica, UNIPI. Best, Francesco Grotto on behalf of the organizers https://sites.google.com/unipi.it/spass ---------------------------------------------------------------- /Abstract: We study a (1+1)-dimensional semi-discrete random variational problem that can be interpreted as the geometrically linearized version of the critical 2-dimensional random field Ising model (at zero temperature). We show that at every dyadic scale from the system size down to the lattice spacing the minimizer contains at most order-one Dirichlet energy per unit length, leading to a logarithmic scaling of the minimal energy. Using super-additivity in the scales, this allows us to establish a quenched homogenization result in the sense that he leading order of the minimal energy becomes deterministic as the ratio system size/lattice spacing diverges. This is joint work with Felix Otto and Christian Wagner./

OWABI - Clara Grazian - November 27 - 11am UK time
by Massimiliano Tamborrino 13 Nov '25

13 Nov '25

Dear all, the next OWABI seminar www.warwick.ac.uk/owabi<http://www.warwick.ac.uk/owabi> is quickly approaching! Our next speaker is Clara Grazian<https://www.sydney.edu.au/science/about/our-people/academic-staff/clara-gra…> (University of Sidney), who will talk about "Approximate Bayesian Computation with Statistical Distances for Model Selection" on Thursday the 27th November at 11am UK time, with an abstract reported below. Abstract: Model selection is a key task in statistics, playing a critical role across various scientific disciplines. While no model can fully capture the complexities of a real-world data-generating process, identifying the model that best approximates it can provide valuable insights. Bayesian statistics offers a flexible framework for model selection by updating prior beliefs as new data becomes available, allowing for ongoing refinement of candidate models. This is typically achieved by calculating posterior probabilities, which quantify the support for each model given the observed data. However, in cases where likelihood functions are intractable, exact computation of these posterior probabilities becomes infeasible. Approximate Bayesian computation (ABC) has emerged as a likelihood-free method and it is traditionally used with summary statistics to reduce data dimensionality, however this often results in information loss difficult to quantify, particularly in model selection contexts. Recent advancements propose the use of full data approaches based on statistical distances, offering a promising alternative that bypasses the need for handcrafted summary statistics and can yield posterior approximations that more closely reflect the true posterior under suitable conditions. Despite these developments, full data ABC approaches have not yet been widely applied to model selection problems. This paper seeks to address this gap by investigating the performance of ABC with statistical distances in model selection. Through simulation studies and an application to toad movement models, this work explores whether full data approaches can overcome the limitations of summary statistic-based ABC for model choice. Keywords: model choice, distance metrics, full data approaches Reference: C. Grazian, Approximate Bayesian Computation with Statistical Distances for Model Selection, preprint at ArXiv:2410.21603, 2025 The talk will be hosted on MS Teams Link: OWABI - Clara Grazian - Approximate Bayesian Computation with Statistical Distances for Model Selection | Meeting-Join | Microsoft Teams<https://teams.microsoft.com/meet/36518340835776?p=V9GRQQoSQKpFBofF2W> Meeting ID: 365 183 408 357 76 Passcode: 6Fg9nW7T Best, Massimiliano on the behalf of the OWABI Organisers ------ Dr. Massimiliano Tamborrino Reader (Associate Professor) and WIHEA Fellow Department of Statistics University of Warwick https://warwick.ac.uk/tamborrino

Seminario Lucas D'Alimonte, Lunedì 17 Novembre, Sapienza Università di Roma
by Silvestri, Vittoria 13 Nov '25

13 Nov '25

Segnalo il seguente seminario, che si terrà Lunedì prossimo in Sapienza. *Lunedì 17 Novembre, ore 16:15,* Sala di Consiglio, Dipartimento di Matematica, Sapienza Università di Roma *Speaker:* Lucas D'Alimonte (LPSM Sorbonne Université) *Title:* Ornstein—Zernike theory for the near-critical planar random cluster model *Abstract:* In this talk, we will discuss the classical Ornstein-Zernike theory for the random-cluster model (also known as FK percolation). In its modern form, it is a very robust theory, which most celebrated output is the computation of the asymptotically polynomial corrections to the pure exponential decay of the two-points correlation function of the random-cluster model in the subcritical regime. We will present an ongoing project that extends this theory to the near-critical regime of the two-dimensional random-cluster model, thus providing a precise understanding of the Ornstein-Zernike asymptotics when papproaches the critical parameter p_c. The output of this work is a formula encompassing both the critical behaviour of the system when looked at a scale negligible with respect to its correlation length, and its subcritical behaviour when looked at a scale way larger than its correlation length. Based on a joint work with Ioan Manolescu. ******************************** Vittoria Silvestri Associate Professor Department of Mathematics University "La Sapienza" Piazzale Aldo Moro, 5 00185 - Rome ********************************
