$W^{}$ and $C^{}$ -superrigidity results for coinduced groups

Ionut Chifan, Alec Diaz-Arias, Daniel Drimbe

In this paper we explore a generic notion of superrigidity for von Neumann algebras $L (G)$ and reduced $C^{*}$ -algebras $C_{r}^{*} (G)$ associated with countable discrete groups $G$ . This…

Product rigidity in von Neumann and C $^{*}$ -algebras via s-malleable deformations

Daniel Drimbe

We provide a new large class of countable icc groups $A$ for which the product rigidity result from [CdSS15] holds: if $Γ_{1}, \dots, Γ_{n} \in A$ and $Λ$ is any group su…

Solid ergodicity and orbit equivalence rigidity for coinduced actions

Daniel Drimbe

We prove that the solid ergodicity property is stable with respect to taking coinduction for a fairly large class of coinduced action. More precisely, assume that $Σ < Γ$ are countab…

Prime II $_{1}$ factors arising from actions of product groups

Daniel Drimbe

We prove that any II $_{1}$ factor arising from a free ergodic probability measure preserving action $Γ ↷ X$ of a product $Γ = Γ_{1} \times \dots \times Γ_{n}$ of icc hyperbolic,…
