Title:
Stopping times and boundary preserving transformations of random walks
Time & Venue:
2016.5.10 15:00-16:00 N613
Abstract:
Given two different random walks on the same group, a priory there is no reason to expect them to have the same Poisson boundary. We shall show that there is a natural class of transformations of random walks (determined by ordinary or, more generally, randomized stopping times) which do not change the Poisson boundary. The related questions and conjectures will also be discussed.
