Jaraden Department of Mathematics, Al-Zaytoonah University of Jordan, P.O.Box 130, Amman, Jordan Journal Article 2023 05 30 In this paper, we use the definition of the concept ``c-Subnormal Subgroup" to study the structure of a given finite group $G$ which contains some $c-$subnormal subgroups. We prove two main theorems, which answer the question of what conditions must hold so that $G$ is an element in a formation $ \mathfrak{U}$ of supersoluble groups. Finally, we state many previous results which can be considered as special cases of these theorems. https://ijgt.ui.ac.ir/article_27757_f121810b410af6306380cecd827573a4.pdf
