Seminario di Roberto Fontana, mercoledì 24 gennaio ore 11 presso CNR IMATI, Milano

The class of Multivariate Bernoulli distributions with given identical margins Roberto Fontana, Politecnico di Torino, Department of Mathematical Sciences roberto.fontana(a)polito.it The main contributions of the work (joint with P. Semeraro, Politecnico di Torino) are algorithms to sample from multivariate Bernoulli distributions and to determine the distributions and bounds of a wide class of indices and measures of probability mass functions. Probability mass functions of exchangeable Bernoulli distributions are points in a convex polytope, and we provide an analytical expression for the extremal points of this polytope. The more general class of multivariate Bernoulli distributions with identical marginal Bernoulli distributions with parameter p is also a convex polytope. However, finding its extremal points is a more challenging task. Our novel theoretical contribution is to use an algebraic approach to find a set of analytically available generators. We also solve the problem of finding the lower bound in the convex order of multivariate Bernoulli distributions with given margins, but with unspecified dependence structure.

Seminar W. Bock - Sapienza, 22-1-2024
by Luisa Beghin 17 Jan '24

17 Jan '24

Dear all, we are pleased to invite you to the following seminar, which can be attended also via Zoom. *Location:* Room n.24, 4th floor, Edificio CU002 (Scienze Statistiche) *Zoom: * https://uniroma1.zoom.us/j/84380852385?pwd=RDBrcVdvelRMM0VmczlXYWgwL2pPZz09 *Time:* *Monday 22nd of January, at 14.30* *Speaker: *Wolfgang Bock (Linnaeus University) *Title:* Recent Results on the Generalized Grey Brownian Motion *Abstract*: Grey Brownian motion was introduced by Schneider in 1990. In his work Schneider showed that indeed the process fulfills a Feynman-Kac like formula for the solution of the fractional heat equation. In the 2000s the process was generalized by Mainardi et al. In 2016 the group of Grothaus established a White Noise like calculus for the process, also introducing spaces of test and generalized functions. In this talk, we will review this recent development and give an overview of the analysis and the most recent results. In an outlook, we give a strategy on how to introduce spaces of regular distributions to obtain a form of regularity theory.

Seminario Padova - Francesco Pedrotti
by alekos.cecchin＠unipd.it 16 Jan '24

16 Jan '24

Buongiorno a tutti, Vorremmo segnalarvi che venerdì prossimo (19 Gennaio) alle ore 14:30 in aula 1BC50 (Torre Archimede, Università di Padova) ci sarà un seminario per il ciclo di seminari in Probabilità e Finanza di: Francesco Pedrotti (Institute of Science and Technology Austria) <https://sites.google.com/view/francescopedrotti/home-page?authuser=0> https://sites.google.com/view/francescopedrotti/home-page?authuser=0 Title: Contractive coupling rates and curvature lower bounds for reversible Markov chains Date: January 19, 2024, at 14:30, room 1BC45 Abstract: Ricci curvature lower bounds for Riemannian manifolds have been linked to many functional inequalities: this has motivated the seminal independent works of Sturm and Lott and Villani, who extended the notion of curvature lower bound and many of its consequences to a large class of metric measure spaces. In spite of its generality, this theory does not apply to Markov chains on discrete spaces; for this reason, several adapted notions of curvature have been proposed, based on different equivalent characterizations of curvature of Riemannian manifolds. Different notions have different pros and cons: e.g., the entropic curvature of Erbar and Maas is hard to compute in some examples, while Olliviers coarse Ricci curvature is not known to imply a modified logarithmic Sobolev inequality. It is still an open problem to compare these notions. In the present work, adapting arguments of a recent article by Conforti, we show how contractive coupling rates (a concept naturally connected to Olliviers curvature) can be used to establish entropic curvature lower bounds for some examples of reversible Markov chains. Vi aspettiamo numerosi! Alberto Chiarini e Alekos Cecchin Sito web del seminario: https://www.math.unipd.it/~chiarini/seminars/
