Journée-séminaire de combinatoire

(équipe CALIN du LIPN, université Paris-Nord, Villetaneuse)

Le 23 octobre 2019 à 10h20 en Amphi Darwin, Dariusz Buraczewski nous parlera de : Large deviations for random walk in random environment

Résumé : In this talk we will discuss recent results concerning large deviations of one-dimensional nearest neighbour random walk in site-random environment. Our main contribution is an extension of large deviation results to precise (rather than logarithmic) asymptotic. We will explain how this result is related to large deviations of branching process in random environment and stochastic recurrence equations.
