Technion Analysis seminar Speaker: Yuri Lima (Weizmann TITLE: Random walks on groups: an Abramov formula. ABSTRACT: Consider a random walk on a group G. If H is a recurrent subgroup, one can define the induced random walk on H. In this talk, we will relate the two random walk entropies. The proof involves the understanding of a general stationary G-space and its induced stationary H-space, and in particular the respective Furstenberg-Poisson boundaries. The result follows from a more general Abramov type formula for this setup. This is a joint work with Yair Hartman and Omer Tamuz. Date: Thursday, April 5 at 2:30 p.m. Place: Amado 919.
