群的Baer-不变量的子群定理

Subgroup Theorems for the Baer-invariant of Groups

Mohammad Reza Rajabzadeh Moghaddam, Behrooz Mashayekhy, Saeed Kayvanfar

摘要:

M. R. Jones和J.Wiegold在[3]中证明了:如果$G$是一个具有有限指标$n$的子群$H$的有限群,则$G$的Schur乘子的$n$次幂$M(G)^n$同构于$M(H)$的一个子群.本文证明了一个类似的结果,中心由中心由$w$群簇,其中$w$是任何外部交换子字。然后利用M.R.R. Moghabu [6]的一个结果,当$c+1$为任意素数或4时,我们将能够推出关于至多为$c$ $(c\geq 1)$类的幂零群簇的Schur型结果(见[4,9])。

英文摘要:

M.R.Jones and J.Wiegold in [3] have shown that if $G$ is a finite group with a subgroup $H$ of finite index $n$, then the $n$-th power of Schur multiplier of $G$, $M(G)^n$, is isomorphic to a subgroup of $M(H)$. In this paper we prove a similar result for the centre by centre by $w$ variety of groups, where $w$ is any outer commutator word. Then using a result of M.R.R.Moghaddam [6], we will be able to deduce a result of Schur's type (see [4,9]) with respect to the variety of nilpotent groups of class at most $c$ $(c\geq 1)$, when $c+1$ is any prime number or 4.
