【摘要】 在这篇文章中,我们引进了弱Doi-Hopf群模和群斜配对等概念,这些是分别作为弱Doi-Hopf模和普通斜配对概念的推广.以此为工具,我们建立了一类广义的D rinfel’d量子偶,这些是一类弱Hopf群余代数.更多还原

【Abstract】 In this paper,we introduce the notions of a weak Doi-Hopf group module and a group skew pair as a respective generalization of a weak Doi-Hopf module and the usual skew pair.We establish a class of generalized Drinfel’d doubles which is a class of weak Hopf group coalgebras by a group skew pair.更多还原
