About the Amenability of the Crossed Product by Coaction;
关于余作用交叉积的顺从性
In this paper , concepts of crossed coproducts and inner coactions of comodule coalgebras over bialgebras are introduced.
提出了双代数上的余模余代数的内余作用和交叉双积的概念 ,给出了交叉余积的一些性质及由内余作用诱导的交叉余积的构造方法 ,还给出了交叉双积的一些性质。
This paper discussed the foundation of bicrossed products with inner action and inner coaction, investigated the conditions of a bicrossed product being to a bismash product, and proved that bismash product is isomophic to Hopf algebra HA.
证明了ＨＢαＡ≌ＨＡ（作为Ｈｏｐｆ代数），并利用内作用、内余作用讨论了ｄｏｕｂｌｅＳｍａｓｈ积ＨβαＡ，其中包括了Ｄｒｉｎｆｅｌ′ｄ的著名例子Ｄ（Ｈ）。
In this paper we study various Smash products constructed by inner action and inner coaction and apply the established theory to showing the duality theorem for Hopf comodule coalgebra under the additional assumption that H is a finite dimensional Hopf algebra.
从研究由内作用、内余作用构造的各种Ｓｍａｓｈ积（包括Ｓｍａｓｈ余积，双Ｓｍａｓｈ积，ＤｏｕｂｌｅＳｍａｓｈ积，ＤｏｕｂｌｅＳｍａｓｈ余积）入手，阐明这些Ｓｍａｓｈ积具有良好的代数性质。
