Given a Lie group G (for example SL(n,R)) a lattice Λ of G (for example SL(n,Z)), the subgroups of G act in the quotient space G/Λ. If Γ is such a subgroup, in some cases, one can give a classification of the Γ-orbits closures. I will give new such examples, in which the classifications follows from the study of random walks in G/Λ. This is a joint work with Yves Benoist.
