Dear Colleagues, we would like to invite you to the following Probability seminar that will take place at the Department of Mathematics of Padova, on February 21. ________________________________________________________ Speaker: Giovanni Conforti (CMAP, École Polytechnique ) Title: Understanding the most likely evolution of interacting particle systems 21 FEBRUARY (Friday), 14:30; ROOM 1BC45, Dipartimento di Matematica “Tullio Levi-Civita”, Via Trieste 63, Padova Abstract: An old question posed by Schrodinger may be rephrased as follows: what is the most likely evolution of an interacting particle system conditionally on the observation of its initial and final configurations? It is often the case that by means Large Deviation Principle this question is rigorously formulated as a (mean field) control problem in the space of probability measures. In the first part of this talk we will see if the space of probability measures is endowed with a Riemannian metric naturally induced by the form of the rate function, the equations governing the most likely evolution take the form of Newton's law. In some examples the Riemannian metric to be considered coincides with the Otto metric of optimal transport, but it is often the case that a different metric has to be chosen. In the second part of the talk we discuss how to use Newton’s laws to obtain convexity principles and dissipation estimates for entropy functionals along the most likely evolution. The interest of these estimates is twofold: on the one hand they imply a novel class of functional inequalities; on the other hand they allow to establish the turnpike property for the control problem defining the most likely evolution and to study its ergodic behaviour. Two concrete examples will be discussed in more detail: the exclusion process and systems of weakly interacting diffusions. Based on joint works with A.Chiarini, I.Gentil, J.Backhoff, C.Léonard, M.Pavon and L. Tamanini. All of you are very welcome.

avviso breve ciclo seminari
by Franco Flandoli 08 Feb '20

08 Feb '20

Si comunica che nei giorni *martedì 11 febbraio (aula Mancini) martedì 18 febbraio (aula Mancini) martedì 25 febbraio (aula Tonelli)* si terranno, presso la Scuola Normale Superiore di Pisa, i seguenti due cicli di seminari, con eventuale proseguimento da concordare: *ore 11-12 Sigurd Assing ore 12-13 Michael Goldman* Il tema dei seminari è brevemente descritto qui di seguito. Tutti gli interessati sono invitati a partecipare. ------------------------ *Sigurd Assing* (University of Warwick) TITLE: Bayesian Gaussian Process Latent Variable Model ABSTRACT: We introduce a variational inference framework for training the Gaussian process latent variable model and thus performing Bayesian nonlinear dimensionality reduction. The maximization of the variational lower bound provides a Bayesian training procedure that is robust to overfitting and can automatically select the dimensionality of the nonlinear latent space. ------------------------ *Michael Goldman* (Université Paris Diderot, CNRS) TITLE: A variational approach to regularity in optimal transport and applications to the optimal matching problem. ABSTRACT: In this course I will present the regularity theory for optimal transport maps recently developed together with M. Huesmann and F. Otto. The main point of the course is to show that as long as we are in a linearization regime, that is as long as the local displacement and the local distances of the two marginals to the Lebesgue measure are small, the displacement is quantitatively close to the gradient of the solution of a Poisson equation. We will see applications both to partial regularity and to (a variant of) the optimal matching problem. In particular, we will see how this theory allows to justify down to the microscopic scale some predictions made by Caracciolo and al for that problem.

Seminario Karim Barigou in Bicocca
by Valeria Bignozzi 06 Feb '20

06 Feb '20

Si avvisa che il giorno Lunedì 10 Febbraio alle ore 15:30 presso l’Università di Milano-Bicocca (via degli Arcimboldi 8 - edificio U7, quarto piano- aula 4026) si terrà il seguente seminario: Speaker: Karim Barigou (University of Lyon) Title: Fair valuation of insurance liabilities: interplay between actuarial judgement and market-consistency Abstract: Insurance liabilities are in most cases (only) partially replicable by traded assets. This may be due to the fact that the payoffs of the underlying insurance contracts are defined in terms of a combination of hedgeable and unhedgeable claims (e.g. unit-linked insurance) or due to the existence of traded insurance-linked securities of which the payoff is correlated with the payoff of the insurance liability (e.g. CAT bonds). Since not all insurance claims can be perfectly replicated by traded assets, we face the problem of valuating claims in incomplete markets (i.e. markets in which some claims are not perfectly hedgeable). The main goal of this presentation is to introduce different valuation frameworks for the determination of a fair valuation for insurance liabilities. The objective of this valuation is to merge the traditional actuarial valuation based on pooling and diversification with a market-consistent approach based on hedging and replication. In particular, we define a fair valuation as a valuation which is market-consistent (marked-to-market for hedgeable claims) and actuarial (marked-to-model for claims independent of financial market evolutions). Among the different fair valuation frameworks, we introduce and investigate the class of `hedge-based valuations'. Under this approach, one unbundles the unhedgeable insurance claim in a hedgeable part and a remaining part. The fair value of the claim is then set equal to the sum of the respective values of the hedgeable and the unhedgeable parts, where the hedgeable part is valuated by the financial price of its underlying hedge, while the value of the remaining part is determined via an actuarial approach. Tutti gli interessati sono invitati a partecipare.
