K-theory for Exceptional Extended Affine Weyl Groups

Affine Weyl groups are a class of groups for which the group C^*-algebra can in principle be understood directly.  I will give an overview of how Langlands duality gives a Poincare duality for these algebras, and discuss the problem of calculating the K-theory for the extended affine Weyl groups for the exceptional Lie group E_6.
