In this paper we completely classify nontrivial semisimple Hopf algebras of dimension 16. We also compute all the possible structures of the Grothendieck ring of semisimple non-commutative Hopf algebras of dimension 16. Moreover, we prove that non-commutative semisimple Hopf algebras of dimension p

β¦ Synopsis
We show that if A is a semisimple Hopf algebra of dimension pq 2 over an algebraically closed field k of characteristic zero, then under certain restrictions either A or A * must have a non-trivial central group-like element. We then classify all semisimple Hopf algebras of dimension pq 2 over k which are not simple as Hopf algebras. We also determine all isomorphism classes of Hopf algebras of dimension pqr obtained as abelian extensions.

This paper makes a contribution to the problem of classifying finitedimensional semisimple Hopf algebras H over an algebraically closed field k of characteristic 0. Specifically, we show that if H has dimension pq for primes p and q, then H is trivial; that is, H is either a group algebra or the dua
For a finite dimensional semisimple cosemisimple Hopf algebra A and its dual Hopf algebra B, we set up a natural one-to-one correspondence between categories with actions of the monoidal categories of representations of A and of B. This gives a categorical interpretation of the duality for actions o
We study the group of group-like elements of a weak Hopf algebra and derive an analogue of Radford's formula for the fourth power of the antipode S; which implies that the antipode has a finite order modulo, a trivial automorphism. We find a sufficient condition in terms of TrΓ°S 2 Γ for a weak Hopf
