设k是特征为0的代数闭域,H为k上的有限维余半单Hopf代数.首先证明了如果H具有型l:1+m:2+1:3+…,则3整除H的维数;其次证明了如果H具有型l:1+m:2+…+1:p+…,且H没有9维的单子余代数,则p整除H的维数,其中p为素数.
Let H be a cosemisimple Hopf algebra over an algebraically closed field k of characteristic zero. This paper shows that if H is of type l: 1 +m : 2+ 1 : 3+…, then its dimension is divisible by 3. It also shows if H is of type l : 1+m: 2+…+1: p+…, and H does not contain simple subcoalgebras of dimension 9, then p divides the dimension of H,where p is prime.
