AI总结:
该研究针对有限群中的弱次正规$p$-子群展开分类工作,进一步刻画含循环弱次正规$p$-子群的有限群,并借助群元素阶的性质推导Baer-Suzuki定理的多种变体,丰富有限群论相关结论。
摘要:
有限群$G$的子群$R$若在$G$中不次正规,但在$G$中$R$的每个真扩群中都次正规,则称$R$在$G$中弱次正规。本文首先对所有包含某个素数$p$对应的弱次正规$p$-子群的有限群$G$进行了分类,随后确定了所有包含循环弱次正规$p$-子群的有限群。作为应用,我们利用某些群元素的阶证明了若干Baer-Suzuki定理的变体。
英文摘要:
A subgroup $R$ of a finite group $G$ is weakly subnormal in $G$ if $R$ is not subnormal in $G$ but it is subnormal in every proper overgroup of $R$ in $G$. In this paper, we first classify all finite groups $G$ which contains a weakly subnormal $p$-subgroup for some prime $p$. We then determine all finite groups containing a cyclic weakly subnormal $p$-subgroup. As applications, we prove a number of variations of the Baer-Suzuki theorem using the orders of certain group elements.
