Abstract
Let \(\mathfrak{F}\) denote a class of groups. A maximal subgroup M of G is called \(\mathfrak{F}\)-abnormal provided G/MG ∉ \(\mathfrak{F}\). We say that (K, H) is an \(\mathfrak{F}\)-abnormal pair of G provided K is a maximal \(\mathfrak{F}\)-abnormal subgroup of H. Let Σ = {G0 ≤ G1 ≤ G2 ≤ … ≤ Gn} be a subgroup series of G. A subgroup H of G is said to be Σ-\(\mathfrak{F}\)-embedded in G if H either covers or avoids every \(\mathfrak{F}\)-abnormal pair (K, H) such that Gi−1≤ K < H ≤ Gi for some i ∈ {0, 1, …, n}. In this paper, some new characterizations of p-supersoluble and p-soluble are given by discussing the properties of Σ-\(\mathfrak{F}\)-embedded of subgroups.
