Equidistribution of digits in powers and Diophantine approximations

Abstract

Given integers $a,b>1$ with $\log_b{a}$ irrational, we investigate the connection between the conjectured asymptotic equidistribution of digits in the base-$b$ expansion of $a^n$ and the (non-)Diophantine properties of the number $\theta_{a,b}=\log_b{a}$.
