The tracial Rokhlin property for an inclusion of unital $C^*$-algebras

Abstract: We introduce and study a notion of Rokhlin property for an inclusion of unital $C^*$-algebras which could have no projections like the Jiang-Su algebra. We also introduce a notion of approximate representability and show a duality between them. We demonstrate the importance of these notions by showing the permanence of the tracial $\mathcal{Z}$-absorbingness and the strict comparison property.
