Abstract:
We describe the geometry of representation of numbers belonging to $(0,1]$ by the positive Lüroth series, i.e., special series whose terms are reciprocal of positive integers. We establish the geometrical meaning of digits, give properties of cylinders, semicylinders and tail sets, metric relations; prove topological, metric and fractal properties of sets of numbers with restrictions on use of “digits”; show that for determination of Hausdorff–Besicovitch dimension of Borel set it is enough to use connected unions of cylindrical sets of the same rank. Some applications of $L$representation to probabilistic theory of numbers are also considered.
Keywords:
Lüroth series, $L$representation, cylinder, semicylinder, shift operator, random variable defined by $L$representation, fractal, Hausdorff–Besicovitch dimension.
