Non-classification of free Araki-Woods factors and -invariants
Román Sasyk, Asger Törnquist, Stefaan Vaes
We define the standard Borel space of free Araki-Woods factors and prove that their isomorphism relation is not classifiable by countable structures. We also prove that equality of…

Rigidity for von Neumann algebras given by locally compact groups and their crossed products
Arnaud Brothier, Tobe Deprez, Stefaan Vaes
We prove the first rigidity and classification theorems for crossed product von Neumann algebras given by actions of non-discrete, locally compact groups. We prove that for arbitra…

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 $…
