Convex cocompact actions in real projective geometry
Jeffrey Danciger, Mathematics Department, University of Texas, Austin
We discuss a theory of convex cocompactness for discrete subgroups of the projective general linear group acting on projective space. These groups display geometric and dynamical behavior similar to convex cocompact groups in rank one Lie groups (hyperbolic geometry) with some interesting differences. Joint work with Francois Gueritaud and Fanny Kassel.
