Title: Compact quantum groups and classifications

Abstract: This talk reports on recent joint work with M. Weber. Any finite dimensional representation of a compact quantum group $\CQG $ induces an action on the Cuntz algebra Od. We combine a recent classification of easy compact quantum groups and Kirchberg-Phillips theory to identify the fixed point algebras in terms of their K-theory.
