Abstract: We show that two separable stably projectionless simple C*-algebras A and B with $gTR(A) \le 1$ and $gTR(B) \le 1$ which satisfy the UCT are isomorphic if and only if they have the isomorphic Elliott… read more here.

Abstract: There is a special local ring E of order 4, without identity for the multiplication, defined by E = a, b | 2a = 2b = 0, a 2 = a, b 2 = b,… read more here.
