  • Some more algebra on ultrafilters in metric spaces 
    Protasov, I. (Algebra and Discrete Mathematics, 2018)
    We continue algebraization of the set of ultrafilters on a metric spaces initiated in [6]. In particular, we define and study metric counterparts of prime, strongly prime and right cancellable ultrafilters from the Stone-Čech ...
  • Spectral properties of partial automorphisms of a binary rooted tree 
    Kochubinska, E. (Algebra and Discrete Mathematics, 2018)
    We study asymptotics of the spectral measure of a randomly chosen partial automorphism of a rooted tree. To every partial automorphism x we assign its action matrix Ax. It is shown that the uniform distribution on eigenvalues ...
  • Square difference labeling of some union and disjoint union graphs 
    Sherman, Z. (Algebra and Discrete Mathematics, 2018)
    The paper deals with methods of constructing square difference labeling of caterpillars and graphs derived from two operations: path union of cycles and disjoint union of stars. The existence of the square difference ...
  • The growth function of the adding machine 
    Skochko, V. (Algebra and Discrete Mathematics, 2018)
    We compute the growth function of the generalized adding machine and show that its generating function is not algebraic.
  • Type conditions of stable range for identification of qualitative generalized classes of rings 
    Zabavsky, B.V. (Algebra and Discrete Mathematics, 2018)
    This article deals mostly with the following question: when the classical ring of quotients of a commutative ring is a ring of stable range 1? We introduce the concepts of a ring of (von Neumann) regular range 1, a ring ...
  • Unimodality polynomials and generalized Pascal triangles 
    Ahmia, M.; Belbachir, H. (Algebra and Discrete Mathematics, 2018)
    This paper is an extension of Boros and Moll’s result “A criterion for unimodality”, who proved that the polynomial P(x + 1) is unimodal.
  • Variants of a lattice of partitions of a countable set 
    Desiateryk, O.O.; Ganyushkin, O.G. (Algebra and Discrete Mathematics, 2018)
    In this paper we consider the ordered by inclusion lattice Part(M) of all partitions of a countable set M. The lattice Part(M) is a semigroup with respect to the operation Λ which maps two partitions to their greatest ...
  • V.I. Yanchevskii is 70

  • Weak equivalence of representations of Kleinian 4-group 
    Plakosh, A. (Algebra and Discrete Mathematics, 2018)
    We give a classification of representations of the Kleinian 4-group up to weak equivalence.
