摘要
让 G 是一个有限群,让 \(\pi \)是一组素数。本文的目的是得到一些结果,这些结果涉及从 G 的 \(\pi\) 元素的共轭类的大小及其乘数的知识中可以收集到多少关于 G 的 \(\pi\) 结构的信息。在其他结果中,我们证明了类大小的多集决定了 G 是否有一个超中心霍尔(\pi \)子群。
Determining Hypercentral Hall Subgroups in Finite Groups
Let G be a finite group, and let \(\pi \) be a set of primes. The aim of this paper is to obtain some results concerning how much information about the \(\pi \)-structure of G can be gathered from the knowledge of the sizes of conjugacy classes of its \(\pi \)-elements and of their multiplicities. Among other results, we prove that this multiset of class sizes determines whether G has a hypercentral Hall \(\pi \)-subgroup.
