Sturmian和Episturmian词的着色问题

A Coloring Problem for Sturmian and Episturmian Words

Aldo de Luca, Elena V. Pribavkina, Luca Q. Zamboni

摘要:

我们考虑以下公开问题的拉姆齐理论的精神:给定一个非周期的无限字$w$,是否存在有限着色的因素,使没有分解的$w$是单色的?我们表明,这样的着色总是存在时,$w$是一个Sturmian字或一个标准的episturmian字。

英文摘要:

We consider the following open question in the spirit of Ramsey theory: Given an aperiodic infinite word $w$, does there exist a finite coloring of its factors such that no factorization of $w$ is monochromatic? We show that such a coloring always exists whenever $w$ is a Sturmian word or a standard episturmian word.
