On the independence of K-theory and stable rank for simple C*-algebras

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/94653We construct a simple, separable, unital, and nuclear C*-algebra with weakly unperforated K_0-group which does not absorb the Jiang-Su algebra Z tensorially. As a result, we obtain a stably finite counter-example to Elliott's classification conjecture for simple, separable, and nuclear C*-algebras.18 pagesOperator Algebras46L35; 46L80On the independence of K-theory and stable rank for simple C*-algebrastext
