Abstract:

We investigate the subset of a discrete quantum group fixing a sequence of finite subsets, and prove that it is a quantum subgroup. Then with this concept we prove a mean ergodic theorem for discrete quantum groups. This generalize the mean ergodic theorem for amenable discrete quantum groups.
