  • An application of the concept of a generalized central element 
    Al-Sharo, Kh.A.; Shemetkova, O. (Algebra and Discrete Mathematics, 2007)
    With the help of the concept of a generalized central element we study finite groups with the given system of S-quasinormally embedded subgroups.
  • Finite groups with a system of generalized central elements 
    Shemetkova, O. (Algebra and Discrete Mathematics, 2004)
    Let H be a normal subgroup of a finite group G. A number of authors have investigated the structure of G under the assumption that all minimal or maximal subgroups in Sylow subgroups of H are well-situated in G. A general ...
  • On S-quasinormally embedded subgroups of finite groups 
    Al-Sharo, Kh.A.; Shemetkova, O.; Xiaolan Yi (Algebra and Discrete Mathematics, 2012)
    Let G be a finite group. A subgroup A is called:1) S-quasinormal in G if A is permutable with all Sylow subgroups in G 2) S-quasinormally embedded in G if every Sylow subgroup of A is a Sylow subgroup of some S-quasinormal ...
