Tensorial Permanence of $K$ -Stability for Diagonal AH-Algebras

Apurva Seth

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

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 $X$ be a compact metric space, and let $A$ be a pure $C^{*}$ -algebra. We show that $C (X, A)$ is pure whenever $A$ is simple; or every quotient of $A$ is stably finite (e.…

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 Î±: Z^d \to Aut(A), such that rc(A)=r…
