Colloquium: Stationary measures and invariant subsets of homogeneous spaces
by Jean Francois Quint (CNRS, Paris 13) in HB 227
Given a Lie group $G$ (for example ${\rm SL}(n,R)$) a lattice $\Lambda$ of $G$ (for example ${\rm SL}(n,Z)$), the subgroups of $G$ act in the quotient space $G/\Lambda$. If $\Gamma$ is such a subgroup, in some cases, one can give a classification of the $\Gamma$-orbits closures. I will give new such examples, in which the classifications follows from the study of random walks in $G/\Lambda$. This is a joint work with Yves Benoist. Host Department: Rice University-Mathematics
