Abstract

We prove a strong classification result for a certain class of CC^{*}-algebras with primitive ideal space N~\widetilde{\mathbb{N}}, where N~\widetilde{\mathbb{N}} is the one-point compactification of N\mathbb{N}. This class contains the class of graph CC^{*}-algebras with primitive ideal space N~\widetilde{\mathbb{N}}. Along the way, we prove a universal coefficient theorem with ideal-related KK-theory for CC^{*}-algebras over N~\widetilde{\mathbb{N}} whose \infty fiber has torsion-free KK-theory.
