SUMMARY:Classifying group actions on Kirchberg algebras - Jamie  Gabe (Uni
 versity of Southern Denmark)

DESCRIPTION:A few years ago\, Szab&oacute\; and I classified all outer ame
 nable discrete group actions on Kirchberg algebras. The classifying invari
 ant is equivariant KK-theory\, so at its core\, the result is a rigidity t
 heorem. I will talk about how one can strengthen the classification in cer
 tain cases and obtain classification with more computable K-theoretic inva
 riants.
