题目：Tunnel effect for semi-classical random walk
报告人：Prof. Hérau Frédéric (Laboratoire de Mathématiques Jean Leray Universite de Mantes)
摘要：We study a semiclassical random walk with respect to a probability measure with a nite number n0 of wells. We show that the associated operator has exactly n0 exponentially close to 1 eigenvalues (in the semiclassical sense), and that the other are O(h) away from 1. We also give an asymptotic of these small eigenvalues. The key ingredient in our approach is a general factorization result of pseudodierential operators, which allows us to use recent results on the Witten Laplacian.
