关于中心自同构均为类保持的有限$p$ -群

On finite $p$-groups whose central automorphisms are all class preserving

Manoj K. Yadav

摘要:

本文得到了关于中心自同构都是类保持的有限$p$ -群的若干结果。特别地,我们证明了:如果$G$是一个有限的$p$ -群,其中心自同构都是类保持的,则$d(G)$是偶数,其中$d(G)$表示$G$的任意极小生成集中的元素个数.作为这些结果的应用,我们得到了自同构都是类保持的有限$p$ -群的一些结果。特别地,我们证明了:如果$G$是一个自同构都是类保持的有限$p$ -群,则$G$的阶至少为$p^8$,且$G$的自同构群的阶至少为$p^12$ .

英文摘要:

We obtain certain results on a finite $p$-group whose central automorphisms are all class preserving. In particular, we prove that if $G$ is a finite $p$-group whose central automorphisms are all class preserving, then $d(G)$ is even, where $d(G)$ denotes the number of elements in any minimal generating set for $G$. As an application of these results, we obtain some results regarding finite $p$-groups whose automorphisms are all class preserving. In particular, we prove that if $G$ is a finite $p$-groups whose automorphisms are all class preserving, then order of $G$ is at least $p^8$ and the order of the automorphism group of $G$ is at least $p^12$.
