|Title:||Topological and metric rigidity for actions of nonabelian groups|
|Seminar:||Geometry Luncheon Seminar|
|Speaker:||Jean-Francois Quint, Paris|
|In this talk, I will present some recent results on the subject above, part of which are jointly due to Yves Benoist and myself. For example, if $\Gamma$ is a non virtually solvable subgroup of $SL(2,\mathbb Z)$ (resp.
$SL(2,\mathbb R)$), every $\Gamma$-orbit in $\mathbb T^2$ (resp.
$SL(2,\mathbb R)/SL(2,\mathbb Z)$) is finite or dense.|
