The notions of a weak Hopf algebra and a smash product over weak Hopf algebra are Introduced.
介绍并研究了弱Hopf代数及其上的冲积概念和性质。
In this paper we study the concept of smash products over weak Hopf algebras and investigate their properties.
本文研究了弱Hopf代数上的冲积并讨论了它约性质。
We prove that the smash product A#H is of the same weak global homological dimension as A, provided that H~* is unimodular and there is a trace one element in A.
当H~*是幺模且A中存在迹为1的元素时,本文证明冲积A#H与代数A的弱整体维数相等。
