  • Trofimuk, A. (Algebra and Discrete Mathematics, 2020)
    Let G be a finite group and P be a p-subgroup of G. If P is a Sylow subgroup of some normal subgroup of G, then we say that P is normally embedded in G. Groups with normally embedded maximal subgroups of Sylow p-subgroup, ...
  • Stocka, A. (Algebra and Discrete Mathematics, 2020)
    A subset X of prime power order elements of a finite group G is called pp-independent if there is no proper subset Y of X such that 〈Y,Ф(G)〉 = 〈X,Ф(G)〉, where Ф(G) is the Frattini subgroup of G. A group G has property Bpp ...
  • Semko, N.N.; Skaskiv, L.V.; Yarovaya, O.A. (Algebra and Discrete Mathematics, 2020)
    Let F be a field, A be a vector space over F and G be a subgroup of GL(F,A). We say that G has a dense family of subgroups, having finite central dimension, if for every pair of subgroups H, K of G such that H ≤ K and H ...
  • Pypka, A A. (Algebra and Discrete Mathematics, 2020)
    In this paper we obtain the description of nonperiodic locally generalized radical groups whose cyclic subgroups are GNA-subgroups.
  • Pratsiovytyi, M.V.; Lysenko, I.M.; Maslova, Yu.P. (Algebra and Discrete Mathematics, 2020)
    In the paper, we consider a two-symbol system of encoding for real numbers with two bases having different signs g₀ < 1 and g₁ = g₀ − 1. Transformations (bijections of the set to itself) of interval [0, g₀] preserving tails ...
  • Lukashova, T. (Algebra and Discrete Mathematics, 2020)
    The author studies groups with given restrictions on norms of decomposable and Abelian non-cyclic subgroups. The properties of non-periodic locally soluble groups, in which such norms are nonidentity and have the identity ...
  • Kurdachenko, L.A.; Subbotin, I.Ya.; Velychko, T.V. (Algebra and Discrete Mathematics, 2020)
    This paper devoted to the non-periodic locally generalized radical groups, whose subgroups of infinite special rank are transitively normal. We proved that if such a group G includes an ascendant locally nilpotent subgroup ...
  • Kniahina, V.N.; Monakhov, V.S. (Algebra and Discrete Mathematics, 2020)
    A Schmidt group is a non-nilpotent group in which every proper subgroup is nilpotent. A subgroup A of a group G is semi-normal in G if there exists a subgroup B of G such that G = AB and AB1 is a proper subgroup of G for ...
  • Biyogmam, G.R.; Tcheka, C. (Algebra and Discrete Mathematics, 2020)
    A Lie subalgebra of a given Leibniz algebra is said to be an absolute maximal Lie subalgebra if it has codimension one. In this paper, we study some properties of non-Lie Leibniz algebras containing absolute maximal Lie ...
  • Akbari, M.; Chen, X.Y.; Moghaddamfar, A.R. (Algebra and Discrete Mathematics, 2020)
    It is proved that nonabelian finite simple groups S with max π(S) = 37 are uniquely determined by their order and degree pattern in the class of all finite groups.
  • Adarchenko, N.M. (Algebra and Discrete Mathematics, 2020)
    Let σ = {σi | i ∈ I} be a partition of the set of all primes ℙ and G a finite group. G is said to be σ-soluble if every chief factor H/K of G is a σᵢ-group for some i = i(H/K). A set H of subgroups of G is said to be a ...
  • Dixon, M.R.; Kurdachenko, L.A.; Semko, N.N.; Subbotin, I.Ya. (Algebra and Discrete Mathematics, 2020)
    In this paper we present a synopsis of some recent results concerned with infinite dimensional liner groups, including generalizations of irreducibility, the central dimension of a linear group, groups with finite dimensional ...
  • Автор відсутній (Algebra and Discrete Mathematics, 2020)
    Leonid A. Kurdachenko is definitely one of the most productive group theorists. His list of publications consists of more than 250 journal articles published in major mathematics journals in many countries including Ukraine, ...
