Abstract
Let G be a finite group and let mathfrakF be a formation of finite groups We say that a subgroup H of G is mathfrakF h normal in G if there exists a normal subgroup T of G such that HT is a normal Hall subgroup of G and H ∩ TH G /H G is contained in the mathfrakF hypercenter Z infty mathfrakF G/H G of G/H G In this paper we obtain some results about the mathfrakF h normal subgroups and then use them to study the structure of finite groups
