内射Hopf双模、infinite dimensional霍普夫代数的上同调和Yoneda积的分次交换性
Injective Hopf bimodules, cohomologies of infinite dimensional Hopf algebras and graded-commutativity of the Yoneda product
摘要：
证明了任意霍普夫代数上的霍普夫双模范畴都有足够的内射子，从而将文献[T1，T2]中关于霍普夫双模上同调统一的一些结果推广到无穷维情形.我们还证明了定义在这些上同调上的杯积是分次交换的。
英文摘要：
We prove that the category of Hopf bimodules over any Hopf algebra has enough injectives, which enables us to extend some results on the unification of Hopf bimodule cohomologies of [T1,T2] to the infinite dimensional case. We also prove that the cup-product defined on these cohomologies is graded-commutative.
