Strong Shift Equivalence of $C^*$-correspondences

Abstract

We define a notion of strong shift equivalence for CC^*-correspondences and show that strong shift equivalent CC^*-correspondences have strongly Morita equivalent Cuntz-Pimsner algebras. Our analysis extends the fact that strong shift equivalent square matrices with non-negative integer entries give stably isomorphic Cuntz-Krieger algebras.
