移位空间之间的开映射

Open maps between shift spaces

Uijin Jung

摘要:

给定一个从移位空间到不可约sofic移位的代码,以下三个条件中的任何两个--开,常数对一,(右或左)闭--都意味着第三个。如果范围不是sofic,那么当双闭性取代闭性时,同样的结果也成立。研究了移位空间之间的开映射的性质。特别是,我们表明,一个封闭的开放(或常数为一)的扩展保留了sofic移位的结构。

英文摘要:

Given a code from a shift space to an irreducible sofic shift, any two of the following three conditions -- open, constant-to-one, (right or left) closing -- imply the third. If the range is not sofic, then the same result holds when bi-closingness replaces closingness. Properties of open mappings between shift spaces are investigated in detail. In particular, we show that a closing open (or constant-to-one) extension preserves the structure of a sofic shift.
