Tensor product decompositions of II factors arising from extensions of amalgamated free product groups
Ionuţ Chifan, Rolando de Santiago, Wanchalerm Sucpikarnon
In this paper we introduce a new family of icc groups which satisfy the following product rigidity phenomenon, discovered in [DHI16] (see also [dSP17]): all tensor product deco…

Amalgamated Free Product Rigidity for Group von Neumann Algebras
Ionut Chifan, Adrian Ioana
We provide a fairly large family of amalgamated free product groups whose amalgam structure can be completely recognized from their von Neumann algebras. Specifica…
