We present a classification theorem for separable amenable simple stably projectionless C∗-algebras with finite nuclear dimension whose K 0 vanish on traces which satisfy the Universal Coefficient Theorem. One of C∗-algebras in the class is denoted by Z 0 which has a unique tracial state, K 0 (Z 0)= Z and K 1 (Z 0)={0}. Let A and B be two separable amenable simple C∗-algebras satisfying the UCT. We show that A⊗ Z 0≅ B⊗ Z 0 if and only if Ell (A⊗ Z 0)= Ell (B⊗ Z 0). A class of simple separable C∗-algebras which are approximately sub-homogeneous whose spectra having bounded dimension is shown to exhaust all possible Elliott invariant for C∗-algebras of the form A⊗ Z 0, where A is any finite separable simple amenable C∗-algebras.
