Résumé

Let $𝔉$ be a non-empty class of groups, $G$ a finite group and $ℒ (G)$ be the lattice of all subgroups of $G$ . A chief factor $H / K$ of $G$ is $𝔉$ -central in $G$ if $(H / K) ⋊ (G / C_{G} (H / K)) \in 𝔉$ . Let $ℒ_{c 𝔉} (G)$ be the set of subgroups $A$ of $G$ such that every chief factor of $G$ between $A^{G}$ and $A_{G}$ is $𝔉$ -central in $G$ ; let $ℒ_{𝔉} (G)$ be the set of subgroups $A$ of $G$ such that $A^{G} / A_{G} \in 𝔉$ . In this paper, we study the influence of $ℒ_{𝔉} (G)$ and $ℒ_{c 𝔉} (G)$ on the structure of $G$ , where $𝔉$ is a normally hereditary saturated formation containing all $σ$ -nilpotent groups and $D = G^{𝔉}$ is $σ$ -soluble. Moreover, we give a new characterization of a finite $σ$ -soluble group to be a $P σ T$ -group.
