  • Zhuchok, Yu.V. (Algebra and Discrete Mathematics, 2013)
    We prove that the monoid of endomorphisms of an arbitrary disconnected hypergraph is isomorphic to a wreath product of a transformation semigroup with a certain small category. For disconnected hypergraphs we also study ...
  • Zatorsky, R.; Stefluk, S. (Algebra and Discrete Mathematics, 2013)
    We consider relations between one class of partition polynomials, parafunctions of triangular matrices (tables), and linear recurrence relations.
  • Schwab, E.D. (Algebra and Discrete Mathematics, 2013)
    The computation of the Möbius function of a Möbius category that arises from a combinatorial inverse semigroup has a distinctive feature. This computation is done on the field of finite posets. In the case of two combinatorial ...
  • Sagi, S. (Algebra and Discrete Mathematics, 2013)
    A convolution is a mapping C of the set Z⁺ of positive integers into the set P(Z⁺) of all subsets of Z⁺ such that every member of C(n) is a divisor of n. If for any n, D(n) is the set of all positive divisors of n, then D ...
  • Nesteruk, V. (Algebra and Discrete Mathematics, 2013)
    In this note, we consider the Tate pairing associated to an isogeny between abelian varieties over pseudofinite field. P. Bruin [1] defined this pairing over finite field k: ker ˆφ(k) × coker(φ(k)) ⟶ k∗, and proved its ...
  • Kozerenko, S. (Algebra and Discrete Mathematics, 2013)
    We investigate graph-theoretical properties of Markov graphs from dynamical systems.
  • Kashu, A.I. (Algebra and Discrete Mathematics, 2013)
    This work is a continuation of the paper [1] (Part I), in which the weakly hereditary and idempotent closure operators of the category R-Mod are described. Using the results of [1], in this part the other classes of closure ...
  • Flores, D.; Paques, A. (Algebra and Discrete Mathematics, 2013)
    In this paper we present an intrinsic description of the structure of an Azumaya skew groupoid ring, having its center contained in the respective ground ring, in terms of suitable central Galois algebras and commutative ...
  • Feng, Yu.; Corsini, P. (Algebra and Discrete Mathematics, 2013)
    For all λ, μ ∈ [0, 1] such that λ < μ, we first introduced the definitions of (λ, μ)-fuzzy ideals and (λ, μ)-fuzzy interior ideals of an ordered Γ-semigroup. Then we proved that in regular and in intra-regular ordered ...
  • Dinesh, T.; Ramakrishnan, T.V. (Algebra and Discrete Mathematics, 2013)
    The concept of graph structure was introduced by E. Sampathkumar in 'Generalised Graph Structures', Bull. Kerala Math. Assoc., Vol 3, No.2, Dec 2006, 65-123. Based on the works of Brouwer, Doob and Stewart, R.H. Jeurissen ...
  • Tamizh Chelvam, T.; Sattanathan, M. (Algebra and Discrete Mathematics, 2013)
    Let G be a group. The power graph ΓP(G) of G is a graph with vertex set V(ΓP(G)) = G and two distinct vertices x and y are adjacent in ΓP(G) if and only if either xˡ = y or yʲ = x, where 2 ≤ i, j ≤ n. In this paper, we ...
  • Brumatti, P.; Veloso, M. (Algebra and Discrete Mathematics, 2013)
    In this note we prove that the ring B²n has non-zero irreducible locally nilpotent derivations, which are explicitly presented, and that its ML-invariant is C.
  • Bondarenko, V.; Kostyshyn, E. (Algebra and Discrete Mathematics, 2013)
    Let p be simple, and let Sp and Tp be the symmetric group and the symmetric semigroup of degree p, respectively. The theorem of this paper says hat the direct product Sp × Tp are of wild representation type over any field ...
  • Ebrahimi Atani, S.; Esmaeili Khalil Saraei, F. (Algebra and Discrete Mathematics, 2013)
    We introduce and investigate the total torsion element graph of semimodules over a commutative semiring with non-zero identity. The main purpose of this paper is to extend the definition and results given in [2] to more ...
