Partial tensor-product functors and crossed-product functors

Operator Algebras 2022-02-18 v2

Abstract

For a given discrete group GG, we apply results of Kirchberg on exact and injective tensor products of CC^*-algebras to give an explicit description of the minimal exact correspondence crossed-product functor and the maximal injective crossed-product functor for GG in the sense of Buss, Echterhoff and Willett. In particular, we show that the former functor dominates the latter.
