When weak Hopf algebras are Frobenius

Miodrag C. Iovanov, Lars Kadison

We investigate when a weak Hopf algebra H is Frobenius; we show this is not always true, but it is true if the semisimple base algebra A has all its matrix blocks of the same dimen…

Semisimple Hopf algebras and their depth two Hopf subalgebras

Lars Kadison

We prove that a depth two Hopf subalgebra K of a semisimple Hopf algebra H is normal (where the ground field is algebraically closed of characteristic zero). This means on the…
