    • Finite groups with seminormal or abnormal Sylow subgroups 

      Monakhov, Victor Stepanovich; Sokhor, Irina (University of Isfahan, 2020)
      Let G be a finite group in which every Sylow subgroup is seminormal or abnormal. We prove that G has a Sylow tower. We establish that if a group has a maximal subgroup with Sylow subgroups under the same conditions, then ...
    • Finite groups with subnormal non-cyclic subgroups 

      Monakhov, Victor; Trofimuk, Alexander (De Gruyter, 2014)
      In this paper we consider finite groups G such that every non-cyclic maximal subgroup in its Sylow subgroups is subnormal in G. In particular, we prove that such solvable groups have an ordered Sylow tower.
