Classification of $\mathcal {O}_\infty $-Stable $C^*$-Algebras Seymour B. Sarason The SAGE Course Companion toPresent a proof of Kirchberg's classification theorem: two separable, nuclear, $\mathcal {O}_\infty $ Stable $C^*$ algebras are stably isomorphic if and only if they are idealrelated KK equivalent. In particular, this provides a more elementary proof of the Kirchberg Phillips theorem which is isolated in the paper to increase readability of this important special case.
