  • Paques, A.; Tamusiunas, T. (Algebra and Discrete Mathematics, 2014)
    In this paper we present a Galois-Grothendiecktype correspondence for groupoid actions. As an application a Galois-type correspondence is also given.
  • Gasiorek, M.; Simson, D.; Zajac, K. (Algebra and Discrete Mathematics, 2014)
    We present symbolic and numerical algorithms for a computer search in the Coxeter spectral classification problems. One of the main aims of the paper is to study finite posets I that are principal, i.e., the rational ...
  • Yegnanarayanan, V. (Algebra and Discrete Mathematics, 2014)
    Given a subset D of positive integers, an integer distance graph is a graph G(Z, D) with the set Z of integers as vertex set and with an edge joining two vertices u and v if and only if |u−v| ∈ D. In this paper we consider ...
  • Davis, N.; Elder, M.; Reeves, L. (Algebra and Discrete Mathematics, 2014)
    We add to the classification of groups generated by 3-state automata over a 2-letter alphabet given by Bondarenko et al., by showing that a number of the groups in the classification are non-contracting. We show that the ...
  • Bondarenko, V.M.; Tylyshchak, A.A.; Stoika, M.V. (Algebra and Discrete Mathematics, 2014)
    We study connections between wildness of the problem of classifying the matrices over an integral domain up to equivalence modulo an ideal and properties of the set of prime elements of the domain.
  • Protasov, I.; Slobodianiuk, S. (Algebra and Discrete Mathematics, 2014)
    Let G be a group and let X be a transitive G-space. We classify the subsets of X with respect to a translation invariant ideal J in the Boolean algebra of all subsets of X, introduce and apply the relative combinatorical ...
  • Abdioglu, C.; Şahinkaya, S.; KÖR, A. (Algebra and Discrete Mathematics, 2014)
    Let R be a ring with an endomorphism σ. We introduce (σ, 0)-multiplication which is a generalization of the simple 0- multiplication. It is proved that for arbitrary positive integers m ≤ n and n ≥ 2, R[x; σ] is a reduced ...
  • Kulazhenko, Yu.I. (Algebra and Discrete Mathematics, 2014)
    In this article new criterian Semiabelian of n-ary Groups is expressed through Self-Returning free point comparatively element specially built to sequences, consisting of mediums of all sides free polygonal figure with ...
  • Umar, A. (Algebra and Discrete Mathematics, 2014)
    Let Xn = {1,2,…,n}. On a partial transformation α : Dom α ⊆ Xn → Im α ⊆ Xn of Xn the following parameters are defined: the breadth or width of α is ∣ Dom α ∣, the collapse of α is c(α) = ∣ ∪t∈Imα{tα⁻¹ :∣ tα⁻¹ ∣≥ 2} ∣, fix ...
