摘要
给定一个有限群G,对群代数kG上的Yetter-Drinfeld单模的结构和分类进行探讨.通过群G的共轭类代表元的中心化子子群上的模构造Yetter-Drinfeld kG-模,并由此给出全部单Yetter-Drinfeld kG-模的结构和同构分类.
Given a finite group G, the structures and classification of Yetter-Drinfeld simple modules over kG are investigated in this paper. It constructs Yetter-Drinfeld kG-modules from modules over the centralizer subgroups of representatives of congrugent classes of G. Then describes the structures of simple Yetter-Drinfeld kG-modules and classifies them up to isomorphism.
