Abstract

In this paper, we study the Lebesgue structure of the distribution of a random variable given in terms of a continued fraction with a two-symbol alphabet {12,1}\{\frac{1}{2}, 1\}, also known as A2A_2-fractions. We establish necessary and sufficient conditions for the distribution to be discrete and provide some sufficient conditions for its singularity. We also explore non-trivial metric properties of the A2A_2-representation with the specified alphabet.
