关于有限$p$ -群对的Schur乘子的指数

On the Exponent of the Schur multiplier of a Pair of Finite $p$-Groups

Fahimeh Mohammadzadeh, Azam Hokmabadi, Behrooz Mashayekhy

摘要:

当$N$在$G$中有补时,本文给出了有限$p$ -群对$(G,N)$的Schur乘子指数的一个上界.作为结果,我们表明,一对$(G,N)$的舒尔乘子的指数整除$\exp(N)$,如果$(G,N)$是一对有限的$p$ -群的类至多$p-1$。我们还证明了,如果$N$是强大的$G$嵌入,那么一对$(G,N)$的舒尔乘子的指数除$\exp(N)$。

英文摘要:

In this paper, we find an upper bound for the exponent of the Schur multiplier of a pair $(G,N)$ of finite $p$-groups, when $N$ admits a complement in $G$. As a consequence, we show that the exponent of the Schur multiplier of a pair $(G,N)$ divides $\exp(N)$ if $(G,N)$ is a pair of finite $p$-groups of class at most $p-1$. We also prove that if $N$ is powerfully embedded in $G$, then the exponent of the Schur multiplier of a pair $(G,N)$ divides $\exp(N)$.
