Some rigidity results for II $_{1}$ factors arising from wreath products of property (T) groups

Ionut Chifan, Bogdan Teodor Udrea

We show that any infinite collection $(Γ_{n})_{n \in N}$ of icc, hyperbolic, property (T) groups satisfies the following von Neumann algebraic \emph{infinite product rigidity}…

A remark on the ultrapower algebra of the hyperfinite factor

Ionut Chifan, Sayan Das

On page 43 in \cite{Po83} Sorin Popa asked whether the following property holds: \emph{If $ω$ is a free ultrafilter on $N$ and $R_{1} \subseteq R$ is an irre…
