  • Generalized equivalence of collections of matrices and common divisors of matrices 
    Petrychkovych, Vasyl‘ M. (Луганский национальный университет им. Т. Шевченко, 2004)
    The collections (A1, ...,Ak) and (B1, ...,Bk) of matrices over an adequate ring are called generalized equivalent if Ai = UBiVi for some invertible matrices U and Vi, i = 1, ..., k. Some conditions are established under ...
  • Generators and ranks in finite partial transformation semigroups 
    Garba, G.U.; Imam, A.T. (2017)
    We extend the concept of path-cycles, defined in [2], to the semigroup Pn, of all partial maps on Xn = {1, 2, . . . , n}, and show that the classical decomposition of permutations into disjoint cycles can be extended ...
  • Genre specifics of «The Adventures of Tom Sawyer» by Mark Twain 
    Liulka, V.; Tarasova, N. (ДЗ "Луганський національний університет імені Тараса Шевченка", 2022-03)
    The article illustrates that “The Adventures of Tom Sawyer” has a number of features characteristic of the novel as a kind of epic: a fairly large volume of work, the epicness of the author's story, full of dialogues ...
  • Geometry of flocks and n-ary groups Sonia Dog 
    Protasov, I. V. (ДЗ "ЛНУ імені Тараса Шевченка", 2019)
    Semiabelinan flocks and n-ary groups are charac- terized by the properties of parallelograms and vectors of the affine geometry defined by these flocks and n-ary groups.
  • Global outer connected domination number of a graph 
    Alishahi, M.; Mojdeh, D. A. (ДЗ "ЛНУ імені Тараса Шевченка", 2018)
    For a given graph G = (V, E), a dominating set D ⊆ V (G) is said to be an outer connected dominating set if D = V (G) or G − D is connected. The outer connected domination number of a graph G, denoted by γec(G), is the ...
  • Globalizations for partial (co)actions on coalgebras 
    Castro, F .; Quadros, G . (ДЗ "ЛНУ імені Тараса Шевченка", 2019)
    In this paper, we introduce the notion of globalization for partial module coalgebra and for partial comodule coalgebra. We show that every partial module coalgebra is globalizable exhibiting a standard globalization. We ...
  • Gorenstein matrices 
    Dokuchaev, M. A.; Kirichenko, V. V.; Zelensky, A. V.; Zhuravlev, V. N. (Луганский национальный университет им. Т. Шевченко, 2005)
    Let A = (aij) be an integral matrix. We say that A is (0, 1, 2)-matrix if aij 2 {0, 1, 2}. There exists the Gorenstein (0, 1, 2)-matrix for any permutation on the set {1, . . . , n} with- out fixed elements. For every ...
  • Gram matrices and Stirling numbers of a class of diagram algebras 
    B i, N . K.; Parvathi, M . (2019)
    In this paper, we introduce Gram matrices for the signed partition algebras, the algebra of Z2-relations and the par- tition algebras. The nondegeneracy and symmetic nature of these Gram matrices are establised. ...
  • Gram matrices and Stirling numbers of a class of diagram algebras 
    Bi, N. K. (2018)
    In the paper [6], we introduced Gram matrices for the signed partition algebras, the algebra of Z2-relations and the partition algebras. (s1, s2, r1, r2, p1, p2)-Stirling numbers of the second kind are also introduced ...
  • Green’s relations on the deformed transformation semigroups 
    Tsyaputa, G. Y. (Луганский национальный университет им. Т. Шевченко, 2004)
  • Green’s relations on the seminearring of full hypersubstitutions of type (n) 
    Changphas, Th.; Denecke, K. (Луганский национальный университет им. Т. Шевченко, 2002-09-23)
  • Groups, in which almost all subgroups are near to normal 
    Semko, M. M.; Kuchmenko, S. M. (Луганский национальный университет им. Т. Шевченко, 2004)
    A subgroup H of a group G is said to be nearly normal, if H has a finite index in its normal closure. These sub- groups have been introduced by B.H. Neumann. In a present paper is studied the groups whose non polycyclic ...
  • Gyrogroups and left gyrogroups as transversals of a special kind 
    Kuznetsov, Eugene (Луганский национальный университет им. Т. Шевченко, 2003-06-15)
  • Homo Lingualis XVI - XVII століть : сучасні дослідження 
    Багнюк, Н. В. (ДЗ "ЛНУ імені Тараса Шевченка", 2018)
    Лінгвістична наукова парадигма XXI століття набула антропоцентричного спрямування. Особливої актуальності набувають питання реконструкції мовної свідомості (індивідуальної, етнічної, суспільної), вивчення природи мовної ...
  • Hyperbolic spaces from self-similar group 
    Nekrashevych, Volodymyr (Луганский национальный университет им. Т. Шевченко, 2003-01-30)
  • H− and R−cross-sections of the full finite semigroup Tn 
    Pyekhtyeryev, Vasyl (Луганский национальный университет им. Т. Шевченко, 2003-07-01)
  • H−,R− and L−cross-sections of the infinite symmetric inverse semigroup ISх 
    Pyekhtyeryev, Vasyl (Луганский национальный университет им. Т. Шевченко, 2005)
    All H−,R− and L−cross-sections of the infinite symmetric inverse semigroup ISX are described.
  • Identities related to integer partitions and complete Bell polynomials 
    Mihoubi, M.; Belbachir, H. (ДЗ"ЛНУ імені Тараса Шевченко", 2017)
    Using the (universal) Theorem for the integer partitions and the q-binomial Theorem, we give arithmetical and combinatorial identities for the complete Bell polynomials as generating functions for the number of partitions ...
  • Improving Economic Security through European Integration Reforms in Ukraine’s Social Sector 
    Tokarskyi, T. (ДЗ "Луганський національний університет", 2020)
    According to the Constitution of Ukraine (Article 1), Ukraine is a democratic, social and rule of law state. Developing a highly developed welfare state in Ukraine re quires shaping its concept model and mechanisms of its ...
