Abstract

Consider the action of GL_d(Z) on the d-dimensional torus R^d/Z^d. Given a probability measure on GL_d(Z) and a point on the torus, a random walk is defined. In this talk, I will report some recent progress about the equidistribution of such random walks. More precisely, I will talk about quantitative results under the assumption that the acting group has semisimple Zariski closure. This is a generalisation of a theorem of Bourgain, Furman, Lindenstrauss and Mozes. This talk is based on a joint work with Nicolas de Saxcé.
