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 ...
