替换不变3iet字的特征

Characterization of substitution invariant 3iet words

P. Baláži, Z. Masáková, E. Pelantová

摘要:

我们研究无限字编码下的轨道交换的三个区间,有充分的复杂性$\C(n)=2n+1$的所有$n\in\N$(非退化3iet字)。利用区间交换的参数和轨道的起始点,我们刻画了在本原替换下不变的3iet字。因此,我们推广了最近获得的结果为sturmian词。

英文摘要:

We study infinite words coding an orbit under an exchange of three intervals which have full complexity $\C(n)=2n+1$ for all $n\in\N$ (non-degenerate 3iet words). In terms of parameters of the interval exchange and the starting point of the orbit we characterize those 3iet words which are invariant under a primitive substitution. Thus, we generalize the result recently obtained for sturmian words.
