  • Some more algebra on ultrafilters in metric spaces 
    Protasov, I . (ДЗ "ЛНУ імені Тараса Шевченка", 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 ...
  • Square difference labeling of some union and disjoint union graphs 
    Sherman, Z. (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. (2018)
    We compute the growth function of the generalized adding machine and show that its generating function is not algebraic.
