On classification of simple non-unital amenable C*-algebras, II

preprint2020arXivOpen access

Abstract

We present a classification theorem for amenable simple stably projectionless C*-algebras with generalized tracial rank one whose K0K_0 vanish on traces which satisfy the Universal Coefficient Theorem. One of them is denoted by Z0{\cal Z}_0 which has a unique tracial state and K0(Z0)=ZK_0({\cal Z}_0)=\mathbb{Z} and K1(Z0)={0}.K_1({\cal Z}_0)=\{0\}. Let AA and BB be two separable simple C∗C^*-algebras satisfying the UCT and have finite nuclear dimension. We show that A⊗Z0≅B⊗Z0A\otimes {\cal Z}_0\cong B\otimes {\cal Z}_0 if and only if Ell(B⊗Z0)=Ell(B⊗Z0).{\rm Ell}(B\otimes {\cal Z}_0)={\rm Ell}(B\otimes {\cal Z}_0). A class of simple separable C∗C^*-algebras which are approximately sub-homogeneous whose spectra having bounded dimension is shown to exhaust all possible Elliott invariant for C∗C^*-algebras of the form A⊗Z0,A\otimes {\cal Z}_0, where AA is any finite separable simple amenable C∗C^*-algebras. Suppose that AA and BB are two finite separable simple C∗C^*-algebras with finite nuclear dimension satisfying the UCT such that traces vanishe on K0(A)K_0(A) and K0(B)K_0(B) (but arbitrary K1K_1). One consequence of the main results in this situation is that A≅BA\cong B if and only if AA and BB have the isomorphic Elliott invariant.
