Description
We examine measure preserving mappings $f$ acting from a probability space $(Ω, F,μ) $ into a probability space $% (Ω^{*},F^{*},μ^{*}) ,$ where $μ^{*}=μ(f^{-1})$. Conditions on $f$, under which $f$ preserves the relations ''to be singular'' and ''to be absolutely continuous'' between measures defined on $(Ω, F) $ and corresponding image measures, are investigated.
We apply the results to investigate the distribution of the random variable $% ξ=\sum\limits^{\infty}_{k=1} ξ_kλ^k,$ where $% λ\in (0;1),$ and $ξ_k$ are independent not necessarily identically distributed random variables taking the values $i$ with probabilities $% p_{ik}$ ,$i=0,1.$
We also studied in details the metric-topological and fractal properties of the distribution of a random variable $ψ= \sum\limits^{\infty}_{k=1} ξ_ka_k,$ where $a_k>0$ are terms of the convergent series.
