  • Semko (Jr.), N.N. (Algebra and Discrete Mathematics, 2013)
    A subgroup H of a group G is said to be transitively normal in G, if H is normal in every subgroup K ≥ H such that H is subnormal in K. The study of radical groups, whose not finitely generated subgroups are transitively ...
  • Kurdachenko, L.A.; Semko (Jr.), N.N.; Subbotin, I.Ya. (Algebra and Discrete Mathematics, 2012)
    A subgroup H of a group G is said to be transitively normal in G, if H is normal in every subgroup K ≥ H such that H is subnormal in K. We described some infinite groups, whose non–finitely generated subgroups are transitively ...
  • M. De Falco; F. de Giovanni; Musella, C. (Algebra and Discrete Mathematics, 2009)
    This paper investigates the structure of groups in which all members of a given relevant set of subgroups are selfnormalizing. In particular, soluble groups in which every nonabelian (or every infinite non-abelian) subgroup ...

    Let G be a group. If S⊆G is a G-invariant subset of G, the factor-group G/CG(S) is called the cocentralizer of S in G. In this survey-paper we review some results dealing with the influence of several cocentralizers on the ...
  • Chernikov, N.S. (2006)
    Для деяких дуже широких класiв D i B ⊂ D груп автор доводить, що довiльна (неабелева) група G ∊ D (вiдповiдно, G ∊ B) задовольняє умову мiнiмальностi для (неабелевих) пiдгруп тодi i тiльки тодi, коли вона є чернiковською.
  • Babai, A.; Khosravi, B. (Український математичний журнал, 2014)
    Let G be a finite group. The prime graph of G is denoted by Γ(G). Let G be a finite group such that Γ(G)=Γ(Dn(5)), where n≥6. In the paper, as the main result, we show that if n is odd, then G is recognizable by the prime ...
  • Dixon, M.R.; Evans, M.J.; Smith, H. (Український математичний журнал, 2002)
    We briefly review some recent works on groups with the weak minimal condition on nonnilpotent subgroups. We also study the class of groups with the weak minimal condition on non-(soluble of derived length d) subgroups.
