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 ********************************
