Weak Hopf algebra symmetries of C^*-algebra inclusions
K. Szlachanyi
After a summary on module algebra actions of C^*-weak Hopf algebras we outline the proof of a reconstruction theorem stating that every finite index depth 2 inclusion N < M of unit…

Finite quantum groupoids and inclusions of finite type
K. Szlachanyi
Bialgebroids, separable bialgebroids, and weak Hopf algebras are compared from a categorical point of view. Then properties of weak Hopf algebras and their applications to finite i…
