Query: Extended Affine Weyl groups, the Baum-Connes correspondence and
  Langlands duality   In this paper we consider the Baum-Connes correspondence for the affine and
extended affine Weyl groups of a compact connected semisimple Lie group. We
show that the Baum-Connes correspondence in this context arises from Langlands
duality for the Lie group.
