摘要

给定整数$b\geqslant 2$和素数的集合$P$，Toeplitz数的集合$T_P$包括$[0，b$$的所有元素，其数字$（a_n）_｛n\geqslant 1｝$在基-$b$展开中对于P$中的所有$P\和$n\geqsant 1｝满足$a_n=a_｛pn｝$1/p=\infty$。然后，我们为差异提供了一个有效的界限。

On simply normal numbers with digit dependencies

Given an integer $b ⩾ 2$ and a set $P$ of prime numbers, the set $T_{P}$ of Toeplitz numbers comprises all elements of [0, b[ whose digits ${(a_{n})}_{n ⩾ 1}$ in the base-b expansion satisfy $a_{n} = a_{p n}$ for all $p \in P$ and $n ⩾ 1$ . Using a completely additive arithmetical function, we construct a number in $T_{P}$ that is simply Borel normal if, and only if, $\sum_{p \notin P} 1 / p = \infty$ . We then provide an effective bound for the discrepancy.

期刊介绍： Mathematika publishes both pure and applied mathematical articles and has done so continuously since its founding by Harold Davenport in the 1950s. The traditional emphasis has been towards the purer side of mathematics but applied mathematics and articles addressing both aspects are equally welcome. The journal is published by the London Mathematical Society, on behalf of its owner University College London, and will continue to publish research papers of the highest mathematical quality.
