Weak Hopf Algebras II: Representation theory, dimensions and the Markov trace
G. Bohm, K. Szlachanyi
If A is a weak C^*-Hopf algebra then the category of finite dimensional unitary representations of A is a monoidal C^*-category with monoidal unit being the GNS representation D_ep…

Weak Hopf Algebras I: Integral Theory and C^*-structure
G. Bohm, F. Nill, K. Szlachanyi
We give an introduction to the theory of weak Hopf algebras proposed recently as a coassociative alternative of weak quasi-Hopf algebras. We follow an axiomatic approach keeping as…
