  • First Baire class functions in the pluri-fine topology 
    Dovgoshey, O.; Küçükaslan, M.; Riihentaus, J. (Труды Института прикладной математики и механики, 2016)
    Let B₁(Ω,R) be the first Baire class of real functions in the pluri-fine topology on an open set Ω ⊆ Cⁿ and let H₁* (Ω,R) be the first functional Lebesgue class of real functions in the same topology. We prove the equality ...
  • On the statistical convergence of metric-valued sequences 
    Kucukaslan, M.; Deger, U.; Dovgoshey, O. (Український математичний журнал, 2014)
    We study the conditions for the density of a subsequence of a statistically convergent sequence under which this subsequence is also statistically convergent. Some sufficient conditions of this type and almost converse ...
  • Uniqueness and topological properties of number representation 
    Dovgoshey, O.; Martio, O.; Ryazanov, V.; Vuorinen, M. (Український математичний вісник, 2004)
    Let b be a complex number with |b| > 1 and let D be a finite subset of the complex plane C such that 0 ∊ D and card D ≥ 2. A number z is representable by the system (D, b) if z = Σajbj , where aj ∊ D. We denote by F the ...
  • Uniqueness of spaces pretangent to metric spaces at infinity 
    Dovgoshey, O.; Bilet, V. (Український математичний вісник, 2019)
    We find the necessary and sufficient conditions under which an unbounded metric space X has, at infinity, a unique pretangent space Ωˣ∞, ř for every scaling sequence ř. In particular, it is proved that Ωˣ∞, ř is unique and ...
