Traces on reduced group C*-algebras
Matthew Kennedy, Sven Raum
In this short note we prove that the reduced group C*-algebra of a locally compact group admits a non-zero trace if and only if the amenable radical of the group is open. This comp…

Measure equivalence and coarse equivalence for unimodular locally compact groups
Juhani Koivisto, David Kyed, Sven Raum
This article is concerned with measure equivalence and uniform measure equivalence of locally compact, second countable groups. We show that two unimodular, locally compact, second…

L^2-Betti numbers of rigid C*-tensor categories and discrete quantum groups
David Kyed, Sven Raum, Stefaan Vaes +1
We compute the -Betti numbers of the free -tensor categories, which are the representation categories of the universal unitary quantum groups . We show that the $…
