Quelques remarques sur les actions analytiques des reseaux des groupes de Lie de rang superieur

Abdelghani Zeghib

All the actions considered here are (real) analytic. Consider a subgroup of finite index of SL(n, Z). We prove, in particular, the (global) homotopical rigidity, for both its stand…

Sur les espaces-temps homogenes

Abdelghani Zeghib

Here, we classify Lie groups acting isometrically on compact Lorentz manifolds, and in particular we describe the geometric structure of compact homogeneous Lorentz manifolds.
