Abstract.
This is a joint work with G. Courtois, S. Gallot and A. Sambusetti. We describe conditions on two manifolds which are quasi isometric to be diffeomorphic. This involves the properties of a map constructed using barycenter and it is related to our work on a curvature-free version of Margulis' lemma.
