Rigidity for von Neumann algebras and their invariants
Vaes, Stefaan
arXiv, 1008.3610 / Harvested from arXiv
We give a survey of recent classification results for crossed product von Neumann algebras arising from measure preserving group actions on probability spaces. This includes II_1 factors with uncountable fundamental groups and the construction of W*-superrigid actions where the crossed product entirely remembers the initial group action that it was constructed from.
