  • Labelling matrices and index matrices of a graph structure 
    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 ...

    Автор відсутній (Algebra and Discrete Mathematics, 2013)
    Ukrainian algebraists with keen sorrow have learned about the death of our colleague, a prominent algebraist and a tremendously efficient science manager of the Republic of Belarus Leonid Aleksandrovich Shemetkov. Leonid ...
  • Leonid Shemetkov. His entire life devotion 
    Skiba, A.N.; Monakhov, V.S.; Selkin, M.V.; Vorob’ev, N.T.; Semenchuk, V.N.; Vasil’ev, A.F. (Algebra and Discrete Mathematics, 2013)
    It is given a short scientific biography of Professor L.A. Shemetkov.
  • On Baer-Shemetkov’s decomposition in modules and related topics 
    Kirichenko, V.V.; Kurdachenko, L.A.; Pypka, A.A.; Subbotin, I.Ya. (Algebra and Discrete Mathematics, 2013)
    This article is dedicated to the memory of an outstanding algebraist Leonid A. Shemetkov. His ideas and results not only shaped modern soluble finite group theory, but significantly influenced other branches of algebra. ...
  • On derived π-length of a finite π-solvable group with supersolvable π-Hall subgroup 
    Monakhov, V.S.; Gritsuk, D.V. (Algebra and Discrete Mathematics, 2013)
    It is proved that if π-Hall subgroup is a supersolvable group then the derived π-length of a π-solvable group G is at most 1 + maxr∈π lαr(G), where lαr(G) is the derived r-length of a π-solvable group G.
  • On elementary domains of partial projective representations of groups 
    Pinedo, H. (Algebra and Discrete Mathematics, 2013)
    We characterize the finite groups containing only elementary domains of factor sets of partial projective representations. A condition for a finite subset A of a group G, which contains the unity of the group, to induce ...
  • On locally nilpotent derivations of Fermat rings 
    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.
  • On Markov graphs 
    Kozerenko, S. (Algebra and Discrete Mathematics, 2013)
    We investigate graph-theoretical properties of Markov graphs from dynamical systems.
  • On maximal and minimal linear matching property 
    Aliabadi, M.; Darafsheh, M.R. (Algebra and Discrete Mathematics, 2013)
    The matching basis in field extentions is introduced by S. Eliahou and C. Lecouvey in [2]. In this paper we define the minimal and maximal linear matching property for field extensions and prove that if K is not algebraically ...
  • On modular representations of semigroups Sp × Tp 
    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 ...
  • On normalizers in fuzzy groups 
    Kurdachenko, L.A.; Grin, K.O.; Turbay, N.A. (Algebra and Discrete Mathematics, 2013)
    In an arbitrary fuzzy group we define the normalizer of fuzzy subgroup and study some its properties. In particular, the characterization of nilpotent fuzzy group has been obtained.
  • On one class of partition polynomials 
    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.
  • On one class of semiperfect semidistributive rings 
    Kasyanuk, M. (Algebra and Discrete Mathematics, 2013)
    In this paper we consider the Artinian semidistributive rings.
  • On some linear groups, having a big family of G-invariant subspaces 
    Kurdachenko, L.A.; Sadovnichenko, A.V. (Algebra and Discrete Mathematics, 2013)
    Let F be a field, A a vector space over F, GL(F, A) be the group of all automorphisms of the vector space A. If B is a subspace of A, then denote by BFG the G-invariant subspace, generated by B. A subspace B is called ...
  • On the relation between completeness and H-closedness of pospaces without infinite antichains 
    Yokoyama, T. (Algebra and Discrete Mathematics, 2013)
    We study the relation between completeness and H-closedness for topological partially ordered spaces. In general, a topological partially ordered space with an infinite antichain which is even directed complete and ...
  • On the structure of skew groupoid rings which are Azumaya 
    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 ...
  • On the Tate pairing associated to an isogeny between abelian varieties over pseudofinite field 
    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 ...
  • Petro Mykhailovych Gudivok 
    Babych, M.; Bondarenko, V.M.; Drozd, Yu.; Kirichenko, V.; Shapochka, I. (Algebra and Discrete Mathematics, 2013)

  • Power graph of finite abelian groups 
    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 ...
  • Reducibility and irreducibility of monomial matrices over commutative rings 
    Bondarenko, V.M.; Bortos, M.Yu.; Dinis, R.F.; Tylyshchak, A.A. (Algebra and Discrete Mathematics, 2013)
