关于univoque self-Sturmian数的注记

A note on univoque self-Sturmian numbers

Jean-Paul Allouche

摘要:

我们比较两组(无限)的二进制序列的后缀满足极值条件:一个发生在研究迭代的单峰连续映射从单位区间到自身,但它也univoque实数的特点;另一个是一个等价的定义的特征Sturmian序列。作为我们研究的一个推论,我们得到了在$(1,2)$中的一个实数$β$是唯一的和自Sturmian的当且仅当1的$β$ -展开式是$1v$的形式,其中$v$是一个以1开始的特征Sturmian序列。

英文摘要:

We compare two sets of (infinite) binary sequences whose suffixes satisfy extremal conditions: one occurs when studying iterations of a unimodal continuous map from the unit interval into itself, but it also characterizes univoque real numbers; the other is an equivalent definition of characteristic Sturmian sequences. As a corollary to our study we obtain that a real number $β$ in $(1,2)$ is univoque and self-Sturmian if and only if the $β$-expansion of 1 is of the form $1v$, where $v$ is a characteristic Sturmian sequence beginning itself in 1.
