摘要
Let p and q be distinct prime numbers. We prove a result on the existence of nontrivial group-like elements in a certain class of semisimple Hopf algebras of dimension pq(r). We conclude the classification of semisimple Hopf algebras A of dimension pq(2) over an algebraically closed field k of characteristic zero, such that both A and A* are of Frobenius type. We also complete the classification of semisimple Hopf algebras of dimension pq(2) < 100.
