S-极限移位

S-limited shifts

Benjamin Matson, Elizabeth Sattler

摘要:

本文研究了$\mathcal{S}$ -极限位移的构造和动力学性质。$S$限制移位是由集合$\mathcal{S} = \{S_1, \ldots, S_p\}$在有限字母表$\mathcal{A} = \{1, \ldots,p\}$上定义的子移位,其中$S_i \subseteq \mathbb{N}$描述了其中可以出现相应字母的块的允许长度.给出了$\mathcal{S}$ -有限移位是有限型或sofic子移位的条件。我们给出了一个精确的公式,找到这样的移位的熵,并表明,一个$\mathcal{S}$有限的移位和它的因素必须是内在遍历。最后,我们给出了两个这样的移位可以共轭的条件,以及共轭$\mathcal{S}$ -限制移位的额外信息。

英文摘要:

In this paper, we explore the construction and dynamical properties of $\mathcal{S}$-limited shifts. An $S$-limited shift is a subshift defined on a finite alphabet $\mathcal{A} = \{1, \ldots,p\}$ by a set $\mathcal{S} = \{S_1, \ldots, S_p\}$, where $S_i \subseteq \mathbb{N}$ describes the allowable lengths of blocks in which the corresponding letter may appear. We give conditions for which an $\mathcal{S}$-limited shift is a subshift of finite type or sofic. We give an exact formula for finding the entropy of such a shift and show that an $\mathcal{S}$-limited shift and its factors must be intrinsically ergodic. Finally, we give some conditions for which two such shifts can be conjugate, and additional information about conjugate $\mathcal{S}$-limited shifts.
