Hopf algebroids with bijective antipodes: axioms, integrals and duals
Gabriella B"ohm, Korn'el Szlach'anyi
Motivated by the study of depth 2 Frobenius extensions we introduce a new notion of Hopf algebroid. It is a 2-sided bialgebroid with a bijective antipode which connects the two, le…

An alternative notion of Hopf algebroid
Gabriella B"ohm
In [1] a new notion of Hopf algebroid has been introduced. It was shown to be inequivalent to the structure introduced under the same name in [17]. We review this new notion of Hop…

Weak C^*-Hopf Algebras and Multiplicative Isometries
G. Bohm, K. Szlachanyi
We show how the data of a finite dimensional weak C^*-Hopf algebra can be encoded into a pair (H,V) where H is a finite dimensional Hilbert space and V: H øH --> H øH is a partial…
