摘要 对任意有限群G的整群环ZG,设Δn(G)是ZG的n次增广理想,记Qn(G)=Δn(G)/Δn+1(G)为G的增广商群.本文给出了Qn(G)的一组与G的Sylowp-子群相关的生成元,并且在利用这组生成元和已有结果的基础上对二面体群D2tk(k奇)之增广商群Qn(D2tk)的结构进行了讨论,证明了Qn(D2tk)Qn(D2t). Let G be a finite group, Z G its integral group ring and △^n (G) the n th power of the augmentation ideal △(G), denote Qn (G) =△^n( G)/△^n+1(G) the augmentation quotient groups of G. In this paper we give a set of generators for △^n (G) related to Sylow p-subgroups of G. Finally the structure of Qn ( D2^tk ) for dihedral group D2^tk is discussed and Qn ( D2^tk) ≌ Qn ( D2^t ) is proved.
