A 1-cohomology characterization of property (T) in von Neumann algebras
Jesse Peterson
We obtain a characterization of property (T) for von Neumann algebras in terms of 1-cohomology similar to the Delorme-Guichardet Theorem for groups.

On the Notion of Relative Property (T) for Inclusions of Von Neumann Algebras
Jesse Peterson, Sorin Popa
We prove that the notion of relative property (T) (or rigidity) for inclusions of finite von Neumann algebras defined in [Po1] is equivalent to a weaker property, in which no ``con…
