On weakly ℋC-embedded subgroups of finite groups
Abstract
Let G be a finite group. A subgroup H of G is said to be an ℋC-subgroup of G if there exists a normal subgroup T of G such that G=HT and Hg∩NT(H)≤H for all g∈G. We say that H is weakly ℋC-embedded in G if there exists a normal subgroup T of G such that HG=HT and Hg∩NT(H)≤H for all g∈G. In this paper, we investigate the structure of the finite group G under the assumption that some subgroups of prime power order are weakly ℋC-embedded in G. Our results improve and generalize several recent results in the literature.
