  • On large indecomposable modules, endo-wild representation type and right pure semisimple rings 
    Simson, D. (Algebra and Discrete Mathematics, 2003)
    The existence of large indecomposable right Rmodules over a right artinian ring R is discussed in connection with the pure semisimplicity problem and the endo-wildness of the category Mod(R) of right R-modules. Some ...
  • On the representation of a number as a sum of the k-th powers in an arithmetic progression 
    Prosyanyuk, N.S. (Algebra and Discrete Mathematics, 2003)
    In this paper we obtain the asymptotic formula for a natural n ≤ x which representate as a sum of two non-negative k-th powers in an arithmetic progression.
  • Tiled orders over discrete valuation rings, finite Markov chains and partially ordered sets. II 
    Chernousova, Zh.T.; Dokuchaev, M.A.; Khibina, M.A.; Kirichenko, V.V.; Miroshnichenko, S.G.; Zhuravlev, V.N. (Algebra and Discrete Mathematics, 2003)
    The main concept of this part of the paper is that of a reduced exponent matrix and its quiver, which is strongly connected and simply laced. We give the description of quivers of reduced Gorenstein exponent matrices ...
  • Flows in graphs and the homology of free categories 
    Husainov, A.A.; Calısıcı, H. (Algebra and Discrete Mathematics, 2003)
    We study the R−module of generalized flows in a graph with coefficients in the R−representation of the graph over a ring R with 1 and show that this R−module is isomorphic to the first derived functor of the colimit. ...
  • On power structures 
    Bosnjak, I.; Madarasz, R. (Algebra and Discrete Mathematics, 2003)
    In general, power structure of a structure A (with universe A) is an appropriate structure defined on the power set P(A). There are lot of papers concerning this topic in which power structures appear explicitly or ...
  • On check character systems over quasigroups and loops 
    Belyavskaya, G.B. (Algebra and Discrete Mathematics, 2003)
    In this article we study check character systems that is error detecting codes, which arise by appending a check digit an to every word a₁a₂...an₋₁ : a₁a₂...an₋₁ → a₁a₂...an₋₁an with the check formula (...((a₁ · δa₂) · δ ...
