On the classification of group actions on C*-algebras up to equivariant KK-equivalence
We study the classification of group actions on C ˚-algebras up to equivariant KK-equivalence.We show that any group action is equivariantly KK-equivalent to an action on a simple, purely infinite C*-algebra.We show that a conjecture of Izumi is equivalent to an equivalence between cocycle conjugacy and equivariant KK-equivalence for actions …
