Seminario di Probabilità - Università di Padova

05 Nov '13

Ho il piacere di invitarvi al seguente seminario, che si terrà lunedì 11 novembre, alle ore 14:30, nell'aula 2BC30 della Torre Archimede presso il Dipartimento di Matematica dell'Università degli Studi di Padova. SPEAKER: Prof. Alessandra Faggionato AFFILIATION: Dip. di Matematica, Roma La Sapienza TITLE: Flows, currents and symmetries for continuous time Markov chains: a large deviation approach. ABSTRACT: We consider a continuous time Markov chain on a countable space (finite or infinite). We focus on the large deviations of the empirical measure, flow and current, as well as their generalization to higher order. In several cases the associated rate function is explicit. As application we investigate the Gallavotti-Cohen functional and its symmetry, and discuss several systems, including birth-and-death Markov chains, random walks on lattices approximating diffusions under an external potential, particle systems. -- Alessandra Bianchi Dip. di Matematica Pura e Applicata Università di Padova Via Trieste, 63 - 35121 Padova, Italy phone: +39 049 827 14 06 fax: +39 049 827 14 28 e-mail: bianchi(a)math.unipd.it http://www.math.unipd.it/~bianchi/

annuncio seminario

cari marco e francesco vi chiederei di far girare sulla mailing list random l'annuncio riportato sotto. grazie alessandra Martedi' 22 ottobre 2013, alle 14.30, nell'Aula B del Dip. di Matematica dell'Universita' La Sapienza, si terra' si seguente seminario Speaker: Pietro Caputo (Universita' di Roma III) Title: Large deviations in sparse random graphs: a local weak convergence approach Abstract: Consider the Erdos-Renyi random graph on n vertices where each edge is present independently with probability p = c/n, with c > 0 fixed. For large n, a typical realization locally behaves like the Galton-Watson tree with Poisson offspring distribution with mean c. We discuss large deviations from this typical behavior, within the framework of the local weak convergence introduced by Benjamini-Schramm and Aldous-Steele. The associated rate function is expressed in terms of an entropy functional on unimodular measures and takes finite values only at measures supported by trees. Along the way, we present a new configuration model which allows one to sample uniform random graphs with a given finite neighborhood distribution, provided the latter is supported by trees. We also present a new class of unimodular random trees, which generalizes the Galton-Watson tree with given degree distribution to the case of neighborhoods of arbitrary finite depth. This is joint work with Charles Bordenave. -- Prof. Alessandra Faggionato Department of Mathematics University La Sapienza Piazzale A. Moro, 2 00186 Rome - Italy

Seminario RUBIO

18 Oct '13

**************************************************************** STATISTICS SEMINARS - COLLEGIO CARLO ALBERTO **************************************************************** Venerdi' 25 ottobre 2013, alle ore 12.00, presso la sala rossa del Collegio Carlo Alberto, Moncalieri (TO), si terra' il seguente seminario: JAVIER RUBIO (University of Warwick) BAYESIAN INFERENCE IN TWO-PIECE AND SKEW-SYMMETRIC DISTRIBUTIONS USING JEFFREYS PRIORS Abstract: We study the Jeffreys prior and the independence Jeffreys prior of general classes of univariate location-scale two-piece and skew-symmetric models. For the case of two-piece models, Jeffreys priors are shown not to allow for Bayesian inference in the wide and practically relevant class of distributions obtained by skewing scale mixtures of normals. Easily checked conditions under which independence Jeffreys priors can be used for valid inference are derived. In the context of scalar skew-symmetric models, it is shown that the Jeffreys prior of the skewness parameter is symmetric about 0, proper, and with tails O(λ^(−3/2)) under mild regularity conditions. Sufficient conditions for the existence of the posterior distribution induced by the independence Jeffreys prior are investigated for the case when the sampling model belongs to the family of skew-symmetric scale mixtures of normal distributions. Joint work with Mark F.J. Steel and Brunero Liseo. Tutti gli interessati sono invitati a partecipare. Il seminario e' organizzato dalla "de Castro" Statistics Initiative (http://www.carloalberto.org/stats) in collaborazione con il Collegio Carlo Alberto. Il programma dei seminari puo' essere consultato alla pagina http://www.carloalberto.org/events/seminars/statistics/ --------- Matteo Ruggiero University of Torino & Collegio Carlo Alberto http://web.econ.unito.it/ruggiero
