  • Benkherouf, L.; Ustimenko, V. (Algebra and Discrete Mathematics, 2002)
    In this paper we present a bound for bipartite graphs with average bidegrees η and ξ satisfying the inequality η ≥ ξ α, α ≥ 1. This bound turns out to be the sharpest existing bound. Sizes of known families of finite ...
  • Protasov, I.V. (Algebra and Discrete Mathematics, 2002)
    A ball structure is a triple (X, P, B), where X, P are nonempty sets and, for any x ∈ X, α ∈ P, B(x, α) is a subset of X, x ∈ B(x, α), which is called a ball of radius α around x. We characterize up to isomorphism the ...
  • Bondarenko, V.M. (Algebra and Discrete Mathematics, 2002)
    In the paper we discuss the notion of “dispersing representation of a quiver” and give, in a natural special case, a criterion for the problem of classifying such representations to be tame. In proving the criterion we ...
  • Dashkova, O.Yu. (Algebra and Discrete Mathematics, 2002)
    In this article the investigation of groups of finite normal rank is continued. The finiteness of normal rank of nonabelian p-group G is proved where G has a normal elementary abelian p-subgroup A for which quotient group ...
  • Lavrenyuk, Y. (Algebra and Discrete Mathematics, 2002)
    The normalizer of the finite state automorphism group of a rooted homogeneous tree in the full automorphism group of this tree was investigated. General form of elements in the normalizer was obtained and countability ...
  • Dudek, W.A.; Young Bae Jun (Algebra and Discrete Mathematics, 2002)
    The notion of k-nil radical in BCH-algebras is defined, and related properties are investigated.
  • Chernousova, Zh.T.; Dokuchaev, M.A.; Khibina, M.A.; Kirichenko, V.V.; Miroshnichenko, S.G.; Zhuravlev, V.N. (Algebra and Discrete Mathematics, 2002)
    We prove that the quiver of tiled order over a discrete valuation ring is strongly connected and simply laced. With such quiver we associate a finite ergodic Markov chain. We introduce the notion of the index in A of a ...
  • Nekrashevych, V. (Algebra and Discrete Mathematics, 2002)
    Dedicated to V. V. Kirichenko on the occasion of his 60th birthday
