摘要
得出了扭曲Smash积模范畴A*HM是辫monoidal范畴的一个充要条件;进一步讨论了与范畴A—HM等价的范畴,引进了广义Yetter-Drinfeld范畴HMC;最后,给出了辫Monoidal范畴上扭曲Smash积构成Hopf代数充要的条件,这些结果统一了量子群中许多重要结论。
A necessary and sufficient condition for the twisted Smash
product modulecategories A H to be a braided monoidal category is given; Furthermore, a classof
category which is equivalent to category A HM is studied. A generalized yetter-Drinfeld category
HMC is introduced. Finally, a necessary and sufficient condition forthe twisted Smash product over
the braided monoidal categories to be Hopf algebra isfound.
