New ArXiv preprint "Extended Affine Weyl groups, the Baum-Connes correspondence and Langlands duality"

Our paper on the relationship between the Baum Connes conjecture and Langlands duality has changed shape (and title) several times, but is now in fairly final form we hope. It is now called Extended Affine Weyl groups, the Baum-Connes correspondence and Langlands duality and you can find its current incarnation on ArXiv at:

This is joint work with Nick Wright and Roger Plymen. From the abstract: 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.
