Note on bi-exactness for creation operators on Fock spaces

In this note, we introduce and study a notion of bi-exactness for creation operators acting on full, symmetric and anti-symmetric Fock spaces. This is a generalization of our previous work, in which

Classification results for nonsingular Bernoulli crossed products

We prove rigidity and classification results for type III factors given by nonsingular Bernoulli actions of the free groups and more general free product groups. This includes a large family of

Bi-Exact Groups, Strongly Ergodic Actions and Group Measure Space Type III Factors with No Central Sequence

AbstractWe investigate the asymptotic structure of (possibly type III) crossed product von Neumann algebras $${M = B \rtimes \Gamma}$$M=B⋊Γ arising from arbitrary actions $${\Gamma \curvearrowright

Ergodic Subequivalence Relations Induced by a Bernoulli Action

Let Γ be a countable group and denote by $${\mathcal{S}}$$ the equivalence relation induced by the Bernoulli action $${\Gamma\curvearrowright [0, 1]^{\Gamma}}$$, where [0, 1]Γ is endowed with the

Asymptotic structure of free Araki–Woods factors

The purpose of this paper is to investigate the structure of Shlyakhtenko’s free Araki–Woods factors using the framework of ultraproduct von Neumann algebras. We first prove that all the free

Solidity of Type III Bernoulli Crossed Products

AbstractWe generalize a theorem of Chifan and Ioana by proving that for any, possibly type III, amenable von Neumann algebra A0, any faithful normal state $${\varphi_0}$$φ0 and any discrete group

Cartan subalgebras of amalgamated free product II$_1$ factors

We study Cartan subalgebras in the context of amalgamated free product II$_1$ factors and obtain several uniqueness and non-existence results. We prove that if $\Gamma$ belongs to a large class of

Bernoulli actions of type III1 and L2-cohomology

We conjecture that a countable group G admits a nonsingular Bernoulli action of type III1 if and only if the first L2-cohomology of G is nonzero. We prove this conjecture for all groups that admit at

Rigidity of free product von Neumann algebras

Let $I$ be any nonempty set and let $(M_{i},\unicode[STIX]{x1D711}_{i})_{i\in I}$ be any family of nonamenable factors, endowed with arbitrary faithful normal states, that belong to a large class

Ergodic theory of affine isometric actions on Hilbert spaces

The classical Gaussian functor associates to every orthogonal representation of a locally compact group G a probability measure preserving action of G called a Gaussian action. In this paper, we
