AI总结:

本文分类了在互素自同构群作用下、含某不变 Sylow 子群正规化子的极大不变子群均为幂零的有限群,并证明该条件等价于所有非幂零极大不变子群均正规。

摘要:

设 $A$ 和 $G$ 为有限群,且 $A$ 通过自同构互素地作用于 $G$。我们给出了有限群 $G$ 的一个完整分类,其中每个包含某个 $A$-不变 Sylow 子群的正规化子的极大 $A$-不变子群都是幂零的。此外,我们证明了以下两个假设是等价的:$G$ 的每个包含某个 $A$-不变 Sylow 子群的正规化子的极大 $A$-不变子群都是幂零的;以及 $G$ 的每个非幂零极大 $A$-不变子群都是正规的。

英文摘要:

Let $A$ and $G$ be finite groups such that $A$ acts coprimely on $G$ by automorphisms. We provide a complete classification of a finite group $G$ in which every maximal $A$-invariant subgroup containing the normalizer of some $A$-invariant Sylow subgroup is nilpotent. Moreover, we show that both the hypothesis that every maximal $A$-invariant subgroup of $G$ containing the normalizer of some $A$-invariant Sylow subgroup is nilpotent and the hypothesis that every non-nilpotent maximal $A$-invariant subgroup of $G$ is normal are equivalent.
