摘要: Let D be a strongly self-absorbing, K1-injective C ¤ -algebra (e.g., the Jiang-Su algebra Z and O1). We characterize, in particular, when A ­ has ideal property, where is separable, purely infinite -algebra. Answering natural question, we prove that there nuclear B such RR(B) = RR(B­Z) sr(B) sr(B­Z) 1 Prim(B) two elements (in basis consisting of compact-open sets) but does not have property. also study some (permanence) properties large classes D-stable -algebras with For ”many” separable characterize RR(C Z) 0.
