任意群的相对第二Fox子群与第三维子群

The relative second Fox and third dimension subgroup of arbitrary groups

Manfred Hartl

摘要:

设$I_R(G)$表示交换环$R$中系数为$G$的群代数$R(G)$的增广理想.对于$G$的任意子群$K$和$H$,我们给出了第三相对维数子群$G\cap(1+I_R(K)I_R(G)+I^3_R(G))$和第二相对维数Fox子群$G\cap(1+I_R(K)I_R(H)+I^2_R(G)I_R(H))$的完整描述.

英文摘要:

Let $I_R(G)$ denote the augmentation ideal of the group algebra $R(G)$ of a group $G$ with coefficients in a commutative ring $R$. We give a complete description of the third relative dimension subgroup $G\cap(1+I_R(K)I_R(G)+I^3_R(G))$ and the second relative Fox subgroup $G\cap(1+I_R(K)I_R(H)+I^2_R(G)I_R(H))$ for any subgroups $K$ and $H$ of $G$.
