DESCRIPTION:Dr. Jean-Marc Schlenker\, University of Luxembourg\nColloque d
 e Mathématiques. Abstract: We will describe three recent and apparently u
 nconnected results: on the combinatorics of polyhedra inscribed in a quad
 ric\, on a canonical extension to the disk of homeomorphisms of the circle
 \, and on the topology of moduli spaces of surface group representations. 
 What those results have in common is that their proofs are all based on 3-
 dimensional anti-de Sitter geometry\, the Lorentzian cousin of hyperbolic 
 geometry. We will briefly describe the historical origin and a few strikin
 g properties of this geometry.
