拟霍普夫代数上Yetter-Drinfeld模的更多性质

More properties of Yetter-Drinfeld modules over quasi-Hopf algebras

D. Bulacu, S. Caenepeel, F. Panaite

摘要:

将霍普夫代数上的Yetter-Drinfeld模的性质推广到拟霍普夫代数上.有限维Yetter-Drinfeld模的对偶也是Yetter-Drinfeld模。在Yetter-Drinfeld模范畴中,通过适当地修改乘法可以得到的代数$H_0$是量子交换的.给出了Yetter-Drinfeld模范畴中Hopf模的一个结构定理,并由此导出了积分的存在唯一性.

英文摘要:

We generalize various properties of Yetter-Drinfeld modules over Hopf algebras to quasi-Hopf algebras. The dual of a finite dimensional Yetter-Drinfeld module is again a Yetter-Drinfeld module. The algebra $H_0$ in the category of Yetter-Drinfeld modules that can be obtained by modifying the multiplication in a proper way is quantum commutative. We give a Structure Theorem for Hopf modules in the category of Yetter-Drinfeld modules, and deduce the existence and uniqueness of integrals from it.
