NPCW04 - Approximation, deformation, quasification

We will discuss a notion of convex cocompactness for discrete groups preserving a properly convex open domain in real projective space. For hyperbolic groups, this notion is equivalent to being the image of a projective Anosov representation. For nonhyperbolic groups, the notion covers Benoist's examples of divisible convex sets which are not strictly convex, as well as their deformations inside larger projective spaces. Even when these groups are nonhyperbolic, they still share some of the good properties of classical convex cocompact subgroups of rank-one Lie groups; in particular, they are quasi-isometrically embedded and structurally stable. This is joint work with J. Danciger and F. Guéritaud.
