On nearly SΦ-normal subgroups of finite groups

M. T. Hussain, S. Ullah

Abstract


Let G be a finite group, H a subgroup of G and HsG the subgroup of H generated by all those subgroups of H which are s-permutable in G. Then we say that H is nearly SΦ-normal in G if G has a normal subgroup T such that HT and H\cap T\leq \Phi (H)H_{sG}. In this paper, we study the structure of group G under the condition that some given subgroups of G are nearly S\Phi-normal in G. Some known results are generalised.

Keywords
