Description

We will study a notion of strong shift equivalence between two Hilbert C^{*}-bimodules as a generalization of strong shift equivalence between two nonnegative matrices. We will prove that if two finite projective Hilbert C^{*}-bimodules are strong shift equivalent, the gauge actions of the C^{*}-algebras of the Hilbert C^{*}-bimodules are stably outer conjugate. Hence the K-theoretic groups of the C^{*}-algebras of strong shift equivalent Hilbert C^{*}-bimodules are invariant.
