本文给出了Pq维Hopf代数的分类,其中p,q是不同的素数。更确切地说,我们证明了:如果p和q是p<q<2p+3的奇素数,则任何Pq维的复Hopf代数都是半单的,从而同构于群代数或群代数的对偶。
In this paper we contribute to the classification of Hopf algebras of dimension pq, where p,q are distinct prime numbers. More precisely, we prove that if p and q are odd primes with p<q<2p+3, then any complex Hopf algebra of dimension pq is semisimple and hence isomorphic to either a group algebra or to the dual of a group algebra by the previous works math.QA/9801129 and math.QA/9801128.
