      On groups with formational subnormal Sylow subgroups 

      Monakhov, Victor Stepanovich; Sokhor, Irina Leonidovna; Сохор, Ирина Леонидовна (De Gruyter, 2018)
      We investigate a finite group G with F-subnormal Sylow subgroups, where F is a subgroup-closed formation and A1A⊆F⊆NA. We prove that G is soluble and the derived subgroup of each metanilpotent subgroup is nilpotent. We ...

      On the residual of a finite group with semi-subnormal subgroups 

      Trofimuk, Alexander (2020)
      A subgroup A of a group G is called seminormal in G, if there exists a subgroup B such that G = AB and AX is a subgroup of G for every subgroup X of B. We introduce the new concept that unites subnormality and seminormality. A ...

      Oт maximal subgroup of a finite solvable subgroup 

      Грицук, Д.В.; Монахов, В.С. (EURASIAN MATHEMATICAL JOURNAL, 2012)
      Let H be a non-normal maximal subgroup of a finite solvable group G, and let q ∈ π(F (H/CoreGH)). It is proved that G has a Sylow q-subgroup Q such that NG(Q) ⊆ H.
