“Semisimple and Co-semisimple Hof algebras”
Finally we will talk about the Maschke’s theorem, namely, if H is a finite dimensional Hopf algebras, then H is semisimple if and only if ε(t) ̸= 0 for any left integral t ∈ H. If there is enough time, we will discuss a dual version of Maschke’s theorem which holds even if H is infinite-dimensional.
