La conjecture de Baum-Connes \`a coefficients pour les groupes   hyperboliques
  This paper gives a proof of the Baum-Connes conjecture with coefficients for hyperbolic groups. More precisely the injectivity of the Baum-Connes map was established by Kasparov and Skandalis and we prove the surjectivity.
