A universal coefficient theorem for actions of finite groups on C*-algebras
Ralf Meyer, George Nadareishvili
The equivariant bootstrap class in the Kasparov category of actions of a finite group G consists of those actions that are equivalent to one on a Type I C*-algebra. Using a result…

Correspondences between graph C*-algebras
Rasmus Bentmann, Ralf Meyer
We describe proper correspondences from graph C*-algebras to arbitrary C*-algebras by K-theoretic data. If the target C*-algebra is a graph C*-algebra as well, we may lift an isomo…
