Regular simple nuclear C*-algebras

Samuel Evington, Shanshan Hua, Christopher Schafhauser +3

We prove Z-stability for all simple, separable, pure, nuclear C*-algebras. Combining this with very recent work of Thiel completes the proof of the Toms-Winter conjecture. We do th…

Pureness of Certain Crossed Product C*-Algebras

Dawn Archey, Julian Buck, Javad Mohammadkarimi +2

We establish comparison and divisibility properties for crossed product C*-algebras arising from automorphisms of algebras C (X, D) which lie over minimal homeomorphisms, from acti…

Continuous functions over a pure C*-algebra

Apurva Seth, Eduard Vilalta

Let be a compact metric space, and let be a pure -algebra. We show that is pure whenever is simple; or every quotient of is stably finite (e.…

Tensorial Permanence of -Stability for Diagonal AH-Algebras

Apurva Seth

We study -stability for tensor products of diagonal AH-algebras with arbitrary C*-algebras. Our main result provides a characterization of -stability: for a diagonal AH-algeb…

The radius of comparison for actions of Z^d on simple AH algebras

M. Ali Asadi-Vasfi, Ilan Hirshberg, Apurva Seth

Given 0 \leq r' \leq r \leq \infty, and d \in N, we construct a simple unital AH algebra A with stable rank one, and a pointwise outer action α: Z^d \to Aut(A), such that rc(A)=r a…

Powers averaging for actions on -algebras

Tattwamasi Amrutam, Ilan Hirshberg, Apurva Seth

Given a unital -algebra discrete group and an action which leaves invariant and such that is simple, and a -co…
