  • Russyev, A. (Algebra and Discrete Mathematics, 2010)
    Representations of finite groups as automata groups over a binary alphabet are investigated. The subclass of groups of automata with no cycles with exit is studied.
  • 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 ...
  • 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 ...

    Let H ≤ E and X be subgroups of a finite group G. Then we say that H is X-quasipermutable (XS-quasipermutable, respectively) in E provided that G has a subgroup B such that E = NE(H)B and H X-permutes with B and with all ...

    Following [1] we say that subgroups H and T of a group G are c-permutable in G if there exists an element x ∈ G such that HTˣ = TˣH. We prove that a finite soluble group G is supersoluble if and only if every maximal ...
  • Cherniak, O.M.; Zasenko, V.I.; Zagorodny, A.G. (Вопросы атомной науки и техники, 2016)
    A test-particle approach to study transport processes in two-dimensional random electric field is proposed. Despite such approach is not as complete as self-consistent one it allows a better control of problem parameters ...
  • Afanas’eva, O.S. (Труды Института прикладной математики и механики, 2016)
    We consider ring Q-homeomorphisms with respect to p-modulus on Finsler manifolds, n - 1 < p < n, and establish sufficient conditions for these mappings to be finitely Lipschitzian.
  • Raievska, I.Yu.; Sysak, Ya.P. (Algebra and Discrete Mathematics, 2012)
    In this paper the metacyclic Miller-Moreno p-groups which appear as the additive groups of finite local nearrings are classified.
  • Raievska, I.I.; Raievska, M.I.; Sysak, Y.P. (Algebra and Discrete Mathematics, 2016)
    In the paper the split metacyclic groups which are the additive groups of finite local nearrings are classified
  • Koçak, D. (Algebra and Discrete Mathematics, 2015)
    In this article, we give two examples of finitely presented quadratic algebras (algebras presented by quadratic relations) of intermediate growth.

  • Belousov, K.I.; Nazarova, L.A.; Roiter, A.V. (Український математичний журнал, 1997)
    We obtain the direct reduction of representations of a dyadic set S such that |Ind C(S)| < ∞ to the bipartite case.
  • Afanas’eva, E.S. (Доповіді НАН України, 2017)
    We study functions of the finite mean oscillation in Finsler spaces with respect to the boundary behavior of ring Q-homeomorphisms.

  • Kapikranian, O.; Berche, B.; Holovatch, Yu. (Вопросы атомной науки и техники, 2007)
    We make a short overview of the recent analytic and numerical studies of the classical two-dimensional XY and Heisenberg models at low temperatures. Special attention is being paid to an influence of finite system size L ...
  • Merdan, Z.; Güzelsoy, E. (Физика низких температур, 2011)
    The four-dimensional Ising model is simulated on the Creutz cellular automaton using the finite-size lattices with the linear dimension 4 ≤ L ≤ 8. The temperature variations and the finite-size scaling plots of the specific ...
  • Bilet V., V.; Dovgoshey O., O. (Український математичний вісник, 2018)
  • Namlyeyeva, Yu.V.; Taranets, R.M.; Yurchenko, V.M. (Физика и техника высоких давлений, 2009)
    A modification of Maxwell’s equations is proposed to describe media with electric and magnetic properties changing essentially under electromagnetic field. It is shown that for such media the electromagnetic waves have ...
  • Hjort, H.H.; Culman, T.G.; Edwards, D.O.; Jizhong He (Физика низких температур, 1997)
    The diffusion coefficient D and the thermal diffusion ratio kT for dilute ⁴He in liquid ³He are calculated from Fermi liquid theory. The collision integral assumes a scattering amplitude a³⁴ expanded in scalar combinations ...
