On the Behavior of the Spectrum of the Limit Frequencies of Digits under Perturbations of a Real Number
L. N. Pushkin Kazan State University
Abstract:
It is shown that, under the action of random digitwise decaying perturbations not changing the spectrum of the limit frequencies of $r$-adic digits, an arbitrary real number written in the $r$-adic number system becomes almost surely normal over all bases multiplicatively independent of $r$.
Keywords:
$r$-adic number system, normal number, digitwise perturbations of a number, spectrum of limit frequencies of digits, Lebesgue measure.
