Obstructions to homomorphisms between homogeneous C*-algebras
Ilan Hirshberg, N. Christopher Phillips
The paper develops a method to detect new obstructions to the existence of homomorphisms between homogeneous C*-algebras with prescribed K‑theory behavior, and uses it to fully res…
An isomorphism theorem for infinite reduced free products
Ilan Hirshberg, N. Christopher Phillips
Let C_1, C_2, ... be a sequence of separable unital C*-algebras, equipped with faithful tracial states and satisfying a mild condition. Let A be a unital direct limit of one dimens…
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…
Simple AH algebras with the same Elliott invariant and radius of comparison
Ilan Hirshberg, N. Christopher Phillips
We construct an uncountable family of pairwise nonisomorphic AH algebras with the same Elliott invariant and same radius of comparison. They can be distinguished by a local radius…
