摘要:

该文引入弱群交叉积的概念, 并给出弱群交叉积代数和通常的张量积余代数构成弱半Hopf群余代数的充要条件, 接着 证明了弱群交叉积上的对偶定理, 推广了沈和王[7, 8]的主要结果.

关键词: 对偶定理, 弱Hopf群余代数, 弱群交叉积

Abstract:

In this paper, the authors introduce the notion of a weak group crossed product and give a sufficient and necessary condition under which weak group crossed product algebras and the usual tensor product coalgebra become a weak semi-Hopf group-coalgebra. Finally, we prove a duality theorem for weak group  crossed products, which extends the main results given by Shen and Wang[7, 8].

Key words: Duality theorem, Weak Hopf group-coalgebra, Weak group crossed product
