Abstract: Доповідь присвячена множинам дійсних чисел з $(0; 1]$, що задані умовами на їхні цифри у різницевому представленні рядами Енгеля. Зокрема, сформульовано та розв'язано задачу про різницеве представлення дійсних чисел рядами Енгеля, яка є аналогічною до задачі Гаусса–Кузьміна щодо ланцюгових дробів.

In the talk, we consider sets of real numbers from $(0, 1]$ defined by conditions on their digits of the difference Engel series representation. In particular, the so-called Gauss–Kuzmin problem for the difference Engel series representation of real numbers is introduced and solved. This is an analogue of the corresponding problem for continued fractions.

Семінар з фрактального аналізу / Fractal analysis seminar

Series comments: Weekly research seminar on fractal analysis (online)

Topics:

  • theory of fractals (fractal geometry and fractal analysis)
  • Hausdorff–Besicovitch dimension, techniques and methods for its calculation and estimation
  • functions and transformations preserving fractal (Hausdorff–Besicovitch, entropic, box-counting, packing, etc.) dimension
  • sets of metric spaces that are essential for functions, sets, and dynamical systems
  • self-similar, self-affine properties of mathematical objects
  • systems of encoding for real numbers (numeral systems) and their applications
  • metric number theory and metric theory of representations of numbers
  • probabilistic number theory and probabilistic theory of representations of numbers
  • measures supported on fractals, particularly singular measures and probability distributions
  • nowhere monotonic and nowhere differentiable functions, functions with fractal properties
  • theory of groups determined by invariants of transformations preserving tails of representation of numbers, digit frequencies, etc.

The talks are mostly in Ukrainian but English is also acceptable
