Abstract

We introduce Rokhlin properties for certain discrete group actions on CC^*-correspondences as well as on Hilbert bimodules and analyze them. It turns out that the group actions on any CC^*-correspondence EE with Rokhlin property induces group actions on the associated CC^*-algebra OE\mathcal O_E with Rokhlin property and the group actions on any Hilbert bimodule with Rokhlin property induces group actions on the linking algebra with Rokhlin property. Permanence properties of several notions such as nuclear dimension and D\mathcal D-absorbing property with respect to crossed product of Hilbert CC^*-modules with groups, where group actions have Rokhlin property, are studied. We also investigate a notion of outerness for Hilbert bimodules.
