ON THE COHOMOLOGY OF ACTIONS OF GROUPS BY BERNOULLI SHIFTS by SORIN POPA* and ROMAN SASYK
نویسنده
چکیده
We prove that if G is a countable, discrete group having infinite, normal subgroups with the relative property (T), then the Bernoulli shift action ofG on Π g∈G (X0, μ0)g for (X0, μ0) an arbitrary probability space, has first cohomology group isomorphic to the character group of G.

We consider cross-product II1 factors M = N⋊σG, with G discrete ICC groups that contain infinite normal subgroups with the relative property (T) and σ : G → AutN trace preserving actions of G on finite von Neumann algebras N that are “malleable” and mixing. Examples are the weighted Bernoulli and Bogoliubov shifts. We prove a rigidity result, showing the uniqueness of the position of L(G) insid...

We consider crossed product II1 factors M = N ⋊σ G, with G discrete ICC groups that contain infinite normal subgroups with the relative property (T) and σ trace preserving actions of G on finite von Neumann algebras N that are “malleable” and mixing. Examples are the actions of G by Bernoulli shifts (classical and non-classical), and by Bogoliubov shifts. We prove a rigidity result for isomorph...

We prove that any isomorphism θ : M0 ≃ M of group measure space II1 factors, M0 = L∞(X0, μ0)⋊σ0 G0, M = L ∞(X,μ)⋊σ G, with G0 containing infinite normal subgroups with the relative property (T) of Kazhdan-Margulis (i.e. G0 w-rigid) and G an ICC group acting by Bernoulli shifts σ, essentially comes from an isomorphism of probability spaces which conjugates the actions with respect to some identi...

For each group G having an infinite normal subgroup with the relative property (T) (for instance groups of the form G = H ×K, where H is infinite with property (T) and K is arbitrary) and each countable abelian group Λ we construct free ergodic measure-preserving actions σΛ of G on the probability space such that the 1’st cohomology group of σΛ, H (σΛ, G), is equal to Char(G)×Λ. We deduce that ...
