Singular subgroups in $A ~_{2}$ -groups and their von Neumann algebras

Yongle Jiang, Piotr W. Nowak

We show that certain amenable subgroups inside $A ~_{2}$ -groups are singular in the sense of Boutonnet and Carderi. This gives a new family of examples of singular group von Ne…

Cohomology groups invariant under continuous orbit equivalence

Yongle Jiang

By the work of Brodzki-Niblo-Nowak-Wright and Monod, topological amenability of a continuous group action can be characterized using uniformly finite homology groups or bounded coh…
