Abstract |
|
An exact sequence of Pimsner for KK-groups of crossed products of C∗-algebras by locally compact groups acting on trees is generalized to the case of crossed products twisted by a circle-valued cocycle. The exact sequence is applied to the case of free products of twisted group C∗-algebras. In particular, the K-groups of the free product of two matrix algebras is computed. |
