Abstract

We introduce a concept of asymptotic mean of digits (symbols) in the $Q_s$-representation of a real number, that is a generalization of the $s$-adic representation and have a self-similar geometry. We discuss its relationship with the frequencies of digits and formulate problems related to the concept. We study the topological, metric, and fractal properties of the set of real numbers that have no asymptotic mean of $Q_s$-symbols. Also we study topological, metric and fractal properties of the sets of real numbers that have asymptotic mean of $Q_3$-symbols which is equal to value of digit frequency of number.
