一组复杂性为$2n+1$的序列

A Set of Sequences of Complexity $2n+1$

Julien Cassaigne, Sébastien Labbé, Julien Leroy

摘要:

我们证明了存在一个三元序列的因素复杂性$2n+1$为任何给定的向量的合理独立的字母频率。根据特定的多维连分数算法,从两个取代的无穷乘积构建这样的序列。我们表明,该算法是共轭的一个众所周知的,Selmer算法。实验(Baldwin,1992)表明它们的第二个李雅普诺夫指数是负的,这预示着有限平衡性质。

英文摘要:

We prove the existence of a ternary sequence of factor complexity $2n+1$ for any given vector of rationally independent letter frequencies. Such sequences are constructed from an infinite product of two substitutions according to a particular Multidimensional Continued Fraction algorithm. We show that this algorithm is conjugate to a well-known one, the Selmer algorithm. Experimentations (Baldwin, 1992) suggest that their second Lyapunov exponent is negative which presages finite balance properties.
