Finite groups with some weakly -supplemented subgroups
Abstract
Let be a finite group. A subgroup of is called -permutable in if permutes with every Sylow subgroup of A subgroup of is called weakly -supplemented in if there exists a subgroup of such that and where is the Frattini subgroup of H and is the subgroup of generated by all these subgroups of that are -permutable in Using this concept, some results for a group to be -nilpotent and supersolvable are given. These results improve and extend some new and recent results in the literature.
