Abstract

Classical Spanier-Whitehead duality was introduced for the stable homotopy category of finite CW complexes. Here we provide a comprehensive treatment of a noncommutative version, termed Spanier-Whitehead KK-duality, which is defined on the category of CC^*-algebras whose KK-theory is finitely generated and that satisfy the UCT with morphisms the KKKK-groups. We explore what happens when these assumptions are relaxed in various ways. In particular, we consider the relationship between Paschke duality and Spanier-Whitehead KK-duality.
