Examples of W and C-superrigid product groups
Jakub Curda, Daniel Drimbe
We provide a new large class of amalgamated free product groups for which the product rigidity result from [CdSS15] holds: if …
Rigidity for von Neumann algebras of graph product groups II. Superrigidity results
Ionut Chifan, Michael Davis, Daniel Drimbe
In \cite{CDD22} we investigated the structure of -isomorphisms between von Neumann algebras associated with graph product groups of flower-shaped graphs and prop…
Rigidity for von Neumann algebras of graph product groups. I. Structure of automorphisms
Ionut Chifan, Michael Davis, Daniel Drimbe
In this paper we study various rigidity aspects of the von Neumann algebra where is a graph product group \cite{Gr90} whose underlying graph is a certain cycle of cliq…
Relative solidity for biexact groups in measure equivalence
Changying Ding, Daniel Drimbe
We demonstrate a relative solidity property for the product of a nonamenable biexact group with an arbitrary infinite group in the measure equivalence setting. Among other applicat…
