摘要
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。该文推广、发展了S .Montgomery等人的结果。
In this paper , concepts of crossed coproducts and inner coactions of comodule coalgebras over bialgebras are introduced. Also the characterizations for crossed coproducts and the method of constructions of crossed coproducts induced by inner coaction are given.Moreover we give some characterizations for crossed biproducts.This paper generalizes and develops the results of S.Montgomery et. al.
