摘要
目的研究自同构导子对有限群结构的影响。方法使用单群分类定理及圈积等手段,分可解群、非可解群两种情况分别讨论。结果证明了Sylow子群的自同构导子是小的有限群恰是幂零群。结论某些特殊子群的自同构导子对有限群的结构具有很强的影响,对自同构导子附加合适条件后,可以得到有限群若干信息。
Objective To investigate the influence of Automizer on the structure of finite groups.Methods By the classification of finite simple groups and wreath product,the groups are divided into solvable and non-solvable groups.Results It proves that finite groups with small automizers for their Sylow subgroups are nilpotent groups.Conclusion The automizers of some subgroups have a strong influence on the structure of finite groups.Adding suitable conditions to automizers can lead to certain information of finite groups.
