kk-Theory for Banach Algebras I: The Non-Equivariant Case
Abstract
kkban is a bivariant K-theory for Banach algebras that has reasonable homological properties, a product and is Morita invariant in a very general sense. We define it here by a universal property and ensure its existence in a rather abstract manner using triangulated categories. The definition ensures that there is a natural transformation from Lafforgue's theory KKban into it so that one can take products of elements in KKban that lie in kkban.
