Factoriality of twisted locally compact group von Neumann algebras
Stefaan Vaes
In this short note, we construct an exotic example of a locally compact group with a Borel -cocycle such that the non-twisted group von Neumann algebra is a facto…
W*-superrigidity for groups with infinite center
Milan Donvil, Stefaan Vaes
We construct discrete groups with infinite center that are nevertheless W*-superrigid, meaning that the group von Neumann algebra fully remembers the group . We obtai…
Borel fields and measured fields of Polish spaces, Banach spaces, von Neumann algebras and C*-algebras
Stefaan Vaes, Lise Wouters
Several recent articles in operator algebras make a nontrivial use of the theory of measurable fields of von Neumann algebras and related structures. This include…
W*-superrigidity for cocycle twisted group von Neumann algebras
Milan Donvil, Stefaan Vaes
We construct countable groups with the following new degree of W*-superrigidity: if is virtually isomorphic, in the sense of admitting a bifinite bimodule, with any othe…
