On an extension of Shlyk's theorem

Jiangtao Shi, Fanjie Xu, Na Li

In this paper, we prove that the intersection of all non-nilpotent maximal subgroups of a non-solvable group containing the normalizer of some Sylow subgroup is nilpotent, which pr…

Finite groups in which every maximal invariant subgroup of order divisible by is nilpotent

Jiangtao Shi, Mengjiao Shan, Fanjie Xu

Let and be finite groups such that acts coprimely on by automorphisms. For any fixed prime divisor of , we provide a complete characterization of the struc…

Finite groups in which some particular non-nilpotent maximal invariant subgroups have indices a prime-power

Jiangtao Shi, Mengjiao Shan, Fanjie Xu

Let and be finite groups such that acts coprimely on by automorphisms, assume that has a maximal -invariant subgroup that is a direct product of some iso…

Finite groups with some particular maximal invariant subgroups being nilpotent or all non-nilpotent maximal invariant subgroups being normal

Jiangtao Shi, Fanjie Xu

Let and be finite groups such that acts coprimely on by automorphisms. We provide a complete classification of a finite group in which every maximal -invaria…

On generalizations of Iwasawa's theorem

Jiangtao Shi, Fanjie Xu, Mengjiao Shan

Iwasawa's theorem indicates that a finite group is supersolvable if and only if all maximal chains of the identity in have the same length. As generalizations of Iwasawa's…
