L²-Betti numbers of coamenable quantum groups

L²-Betti numbers of coamenable quantum groups

We prove that a compact quantum group is coamenable if and only if its corepresentation ring is amenable. We further propose a Følner condition for compact quantum groups and prove it to be equivalent to coamenability. Using this Følner condition, we prove that for a coamenable compact quantum group...
