DESCRIPTION:Bernhard Leeb (LMU Munich)\nGeometry and Dynamics Seminar\nAbs
 tract: I will first discuss Kleinian groups acting on the hyperbolic space
 .  A rich and particularly well-behaved class are the so-called  convex 
 cocompact groups. This class admits a number of rather  different equival
 ent characterizations in terms of geometry and  dynamics. I will then exp
 lain that some of these characterizations remain useful for discrete subgr
 oups C<G of isometry  groups of higher rank symmetric spaces\, such as G=
 SL(n\,R). They  yield an interesting class of subgroups which turns out t
 o coincide  with the (images of the) Anosov representations introduced by
   Labourie and generalized by Guichard and Wienhard. If time permits\, I 
 will present results\, of geometric invariant theory flavour\, on  the dy
 namics of such subgroups on the associated flag manifolds.  This is joint
  work with Misha Kapovich and Joan Porti.
