Relative Haagerup property for arbitrary von Neumann algebras
Martijn Caspers, Mario Klisse, Adam Skalski +2
We introduce the relative Haagerup approximation property for a unital, expected inclusion of arbitrary von Neumann algebras and show that if the smaller algebra is finite then the…

Second cohomology groups of the Hopf-algebras associated to universal unitary quantum groups
Biswarup Das, Uwe Franz, Anna Kula +1
We compute the second (and the first) cohomology groups of -algebras associated to the universal quantum unitary groups of not neccesarily Kac type, extending our earlier resul…

Classifying right-angled Hecke C*-algebras via K-theoretic invariants
Sven Raum, Adam Skalski
Exploiting the graph product structure and results concerning amalgamated free products of C*-algebras we provide an explicit computation of the K-theoretic invariants of right-ang…
