摘要: This paper studies the descriptive set-theoretical complexity of isomorphism problem for separable C*-algebras. We prove that (simple, AI) C*-algebras is complete in class orbit equivalence relations. means any arising from a continuous action completely metrizable group can be reduced to simple, AI
