Rokhkin inclusions with integer and non-integer index

H. Lee, H. Osaka, T. Teruya

We construct new examples of inclusions of unital $C\sp*$-algebras of index-finite type with the Rokhlin property motivated by a broader attempt to understand the range of such inc…

Free coactions of a finite dimensional -Hopf algebra and strong Morita equivalence

Kazunori Kodaka, Tamotsu Teruya

We shall introduce a notion of free coactions of a finite dimensional -Hopf algebra on a -algebra modifying a notion of free actions of a discrete group on a -algebr…

The Rokhlin property for inclusions of C*-algebras

Hiroyuki Osaka, Tamotsu Teruya

Let be an inclusion of -unital C*-algebras with a finite index in the sense of Izumi. Then we introduce the Rokhlin property for a conditional expectation from…

Coactions of a finite dimensional -Hopf algebra on unital -algebras, unital inclusions of unital -algebras and the strong Morita equivalence

Kazunori Kodaka, Tamotsu Teruya

Let and be unital -algebras and let be a finite dimensional -Hopf algebra. Let be its dual -Hopf algebra. Let and be twisted coac…

The strong Morita equivalence for inclusions of -algebras and conditional expectations for equivalence bimodules

Kazunori Kodaka, Tamotsu Teruya

We shall introduce the notions of the strong Morita equivalence for unital inclusions of unital -algebras and conditional expectations from an equivalence bimodule onto its cl…

The strong Morita equivalence for coactions of a finite dimensional -Hopf algebra on unital -algebras

Kazunori Kodaka, Tamotsu Teruya

Following Jansen and Waldmann, and Kajiwara and Watatani, we shall introduce notions of coactions of a finite dimensional -Hopf algebra on a Hilbert -bimodule of finite t…
