Rigidity for von Neumann algebras of graph product groups. I. Structure of automorphisms

  title={Rigidity for von Neumann algebras of graph product groups. I. Structure of automorphisms},
  author={Ionut Chifan and Michael W. Davis and Daniel Drimbe},
In this paper we study various rigidity aspects of the von Neumann algebra L p Γ q where Γ is a graph product group [Gr90] whose underlying graph is a certain cycle of cliques and the vertex groups are the wreath-like product property (T) groups introduced recently in [CIOS21]. Using an approach that combines methods from Popa’s defor-mation/rigidity theory with new techniques pertaining to graph product algebras, we describe all symmetries of these von Neumann algebras and reduced C…

The CCAP for graph products of operator algebras

. For a simple graph Γ and for unital C * -algebras with GNS-faithful states p A v ,ϕ v q for v P V Γ, we consider the reduced graph product p A ,ϕ q “ ˚ v, Γ p A v ,ϕ v q , and show that if every C



Some Applications of Group Theoretic Rips Constructions to the Classification of von Neumann Algebras

In this paper we study various von Neumann algebraic rigidity aspects for the property (T) groups that arise via the Rips construction developed by Belegradek and Osin in geometric group theory

Wreath-like product groups and rigidity of their von Neumann algebras

We introduce a new class of groups, which we call {\it wreath-like products}. These groups are close relatives of the classical wreath products and arise naturally in the context of group theoretic

We survey some of the progress made recently in the classification of von Neumann algebras arising from countable groups and their measure preserving actions on probability spaces. We emphasize

Tits alternatives for graph products

We discuss various types of Tits Alternative for subgroups of graph products of groups, and prove that, under some natural conditions, a graph product of groups satisfies a given form of Tits

Deformation and rigidity for group actions and von Neumann algebras

We present some recent rigidity results for von Neumann algebras (II1 factors) and equivalence relations arising from measure preserving actions of groups on probability spaces which satisfy a

Strong rigidity of II1 factors arising from malleable actions of w-rigid groups, I

We consider crossed product II1 factors $M = N\rtimes_{\sigma}G$, with G discrete ICC groups that contain infinite normal subgroups with the relative property (T) and σ trace preserving actions of G

Graph products of groups

In the 1970's Baudisch introduced the idea of the semifree group, that is, a group in which the only relators are commutators of generators. Baudisch was mainly concerned with subgroup problems,

Proper proximality for various families of groups

In this paper, the notion of proper proximality (introduced in [BIP18]) is studied and classified in various families of groups. We show that if a group acts non-elementarily by isometries on a tree

Rigidity results for Bernoulli actions and their von Neumann algebras (after Sorin Popa)

We survey Sorin Popa's recent work on Bernoulli actions. The paper was written on the occasion of the Bourbaki seminar. Using very original methods from operator algebras, Sorin Popa has shown that
