A class of II factors without non-trivial crossed product decompositions
Adriana Fernández Quero, Adrian Ioana, Hui Tan
We introduce a class of separable II factors admitting no non-trivial crossed product decompositions: , for any trace preserving action $G\curvearro…
Structural and non-isomorphism results for -Araki-Woods factors
Changying Ding, Hui Tan
It is proved that the -Araki-Woods factor $Γ_q(\sH_\R, U)''$ associated with a strongly continuous orthogonal representation $U:\R\to \cO(\sH_\R)$ is strongly solid for all $q\i…
W-superrigidity for property (T) groups with infinite center
Ionuţ Chifan, Adriana Fernández Quero, Denis Osin +1
We propose to study a natural version of Connes' Rigidity Conjecture that involves property (T) groups with infinite center. Utilizing techniques at the intersection of von Neumann…
Rigidity results for group von Neumann algebras with diffuse center
Ionuţ Chifan, Adriana Fernández Quero, Hui Tan
We introduce the first examples of groups with infinite center which in a natural sense are completely recognizable from their von Neumann algebras, . Specifica…
