DESCRIPTION: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 co
 vers Benoist&#39\;s examples of divisible convex sets which are not strict
 ly convex\, as well as their deformations inside larger projective spaces.
  Even when these groups are nonhyperbolic\, they still share some of the g
 ood properties of classical convex cocompact subgroups of rank-one Lie gro
 ups\; in particular\, they are quasi-isometrically embedded and structural
 ly stable. This is joint work with J. Danciger and F. Gu&eacute\;ritaud.
