Poisson boundary of $GL_d(\Q)$

Probability 2009-11-17 v2

Abstract

We construct the Poisson boundary for a random walk supported by the general linear group on the rational numbers as the product of flag manifolds over the pp-adic fields. To this purpose, we prove a law of large numbers using the Oseledets' multiplicative ergodic theorem.
