Classifiability of crossed products by nonamenable groups

  title={Classifiability of crossed products by nonamenable groups},
  author={Eusebio Gardella and Shirly Geffen and Julian J Kranz and P. E. Naryshkin},
We show that all amenable, minimal actions of a large class of nonamenable countable groups on compact metric spaces have dynamical comparison. This class includes all nonamenable hyperbolic groups, many HNNextensions, nonamenable Baumslag-Solitar groups, a large class of amalgamated free groups, lattices in many Lie groups, Ã2-groups, as well as direct products of the above with arbitrary countable groups. As a consequence, crossed products by amenable, minimal and topologically free actions…

Tracially amenable actions and purely infinite crossed products

. We introduce the notion of tracial amenability for actions of discrete groups on unital, tracial C ∗ -algebras, as a weakening of amenability where all the relevant approximations are done in the

Wreath products, allostery and amenability

A countable group is allosteric if it admits a minimal action on a compact space with an ergodic invariant measure, which is topologically free but not essentially free. We prove that if Λ is a

Amenable wreath products with non almost finite actions of mean dimension zero

Almost finiteness was introduced in the seminal work of Kerr as an dynamical analogue of Z -stability in the Toms-Winter conjecture. In this article, we provide the first examples of minimal,

The modern theory of Cuntz semigroups of C*-algebras

We give a detailed introduction to the theory of Cuntz semigroups for C-algebras. Beginning with the most basic definitions and technical lemmas, we present several results of historical importance,

Dynamical comparison and $\mathcal{Z}$-stability for crossed products of simple $C^*$-algebras

. We establish Z -stability for crossed products of outer actions of amenable groups on Z -stable C ∗ -algebras under a mild technical assumption which we call McDuff property with respect to

Let α : G ↷ X \alpha : G\curvearrowright X be a continuous action of an infinite countable group on a compact Hausdorff space. We show that, under the hypothesis that the action

Property P nai v e for acylindrically hyperbolic groups

We prove that every acylindrically hyperbolic group that has no non-trivial finite normal subgroup satisfies a strong ping pong property, the P nai v e property: for any finite collection of elements h

It is shown that the inline-formula content-type is a separable compact Hausdorff space and is a countable infinite discrete amenable group that has the Uniform Rokhlin Property (URP) and Cuntz comparison of open sets (COS).

Topological boundaries of connected graphs and Coxeter groups.

We introduce and study certain topological spaces associated with connected rooted graphs. These spaces reflect combinatorial and order theoretic properties of the underlying graph and relate in the

A characterization of high transitivity for groups acting on trees

We establish a sharp sufficient condition for groups acting on trees to be highly transitive when the action on the tree is minimal of general type. This give new examples of highly transitive

Purely infinite C*-algebras arising from dynamical systems

Nous donnons une condition suffisante pour que la C*-algebre reduite associee a un groupoide r-discret soit purement infinie. Comme application, nous obtenons de nombreux exemples de C*-algebres
