  • On elements of high order in general finite fields 
    Popovych, R. (Algebra and Discrete Mathematics, 2014)
  • The endomorphisms monoids of graphs of order n with a minimum degree n − 3 
    Pipattanajinda, N.; Knauer, U.; Gyurov, B.; Panma, S. (Algebra and Discrete Mathematics, 2014)
    We characterize the endomorphism monoids, End(G), of the generalized graphs G of order n with a minimum degree n − 3. Criteria for regularity, orthodoxy and complete regularity of those monoids based on the structure of G ...
  • A nilpotent non abelian group code 
    Nebe, G.; Schäfer, A. (Algebra and Discrete Mathematics, 2014)
    The paper reports an example for a nilpotent group code which is not monomially equivalent to some abelian group code.
  • A geometrical interpretation of infinite wreath powers 
    Mikaelian, V.H. (Algebra and Discrete Mathematics, 2014)
    A geometrical construction based on an infinite tree graph is suggested to illustrate the concept of infinite wreath powers of P.Hall. We use techniques based on infinite wreath powers and on this geometrical constriction ...
  • Morita equivalence for partially ordered monoids and po-Γ-semigroups with unities 
    Gupta, S.; Sardar, S.K. (Algebra and Discrete Mathematics, 2014)
    We prove that operator pomonoids of a po-Γ-semigroup with unities are Morita equivalent pomonoids. Conversely, we show that if L and R are Morita equivalent pomonoids then a po-Γ-semigroup A with unities can be constructed ...
  • Additivity of Jordan elementary maps on standard rings 
    Ferreira, B.L.M.; Guzzo Jr., H.; Ferreira, J.C.M. (Algebra and Discrete Mathematics, 2014)
    We prove that Jordan elementary surjective maps on standard rings are additive.
  • Exponent matrices and Frobenius rings 
    Dokuchaev, M.A.; Kasyanuk, M.V.; Khibina, M.A.; Kirichenko, V.V. (Algebra and Discrete Mathematics, 2014)
    We give a survey of results connecting the exponent matrices with Frobenius rings. In particular, we prove that for any parmutation σ ∈ Sn there exists a countable set of indecomposable Frobenius semidistributive rings Am ...
  • Lattices of partial sums 
    Chiaselotti, G.; Gentile, T.; Oliverio, P.A. (Algebra and Discrete Mathematics, 2014)
    In this paper we introduce and study a class of partially ordered sets that can be interpreted as partial sums of indeterminate real numbers. An important example of these partially ordered sets, is the classical Young ...
  • On types of local deformations of quadratic forms 
    Bondarenko, V.M. (Algebra and Discrete Mathematics, 2014)
    We consider some aspects of the theory of quadratic forms concerning their local deformations.
  • On the Lie ring of derivations of a semiprime ring 
    Artemovych, O.D.; Kular, K. (Algebra and Discrete Mathematics, 2014)
    We prove that the Lie ring of derivations of a semiprime ring is either trivial or non-nilpotent.
  • On one class of algebras 
    Zhuchok, Yul.V. (Algebra and Discrete Mathematics, 2014)
    In this paper a g-dimonoid which is isomorphic to the free g-dimonoid is given and a free n-nilpotent g-dimonoid is constructed. We also present the least n-nilpotent congruence on a free g-dimonoid and give numerous ...
  • Colour class domination numbers of some classes of graphs 
    Venkatakrishnan, Y.; Swaminathan, V. (Algebra and Discrete Mathematics, 2014)
    We compute the colour class domination number of fan graphs, double fan graphs, Helm graphs, flower graphs and sun flower graphs.
