Anosov representations and proper actions
Fanny Kassel
(University of Lille 1)
Abstract
Anosov representations of word hyperbolic groups into semisimple Lie groups provide a generalization of convex cocompact representations to higher real rank. I will explain how these representations can be used to construct properly discontinuous actions on homogeneous spaces. In certain cases, all properly discontinuous actions of quasi-isometrically embedded groups come from this construction. This is joint work with F. Guéritaud, O. Guichard, and A. Wienhard.
