Invariant subsets under compact quantum group actions

Abstract

We investigate compact quantum group actions on unital CC^*-algebras by analyzing invariant subsets and invariant states. In particular, we come up with the concept of compact quantum group orbits and use it to show that countable compact metrizable spaces with infinitely many points are not quantum homogeneous spaces.
