NPC - Non-positive curvature group actions and cohomology

A geodesic space has thin triangles if every triple of points belongs to the vertex set of a thin triangle. If such a space admits a structure of space with walls, then it is at finite Hausdorff distance of its associated median space. This shows for instance that the hyperbolic n-space is at finite Hausdorff distance from the associated median space.   Joint work with Cornelia Drutu and Frederic Haglund.
