与M-步移位空间不共轭的(M + 1)-步移位空间

(M + 1)-step shift spaces that are not conjugate to M-step shift spaces

Daniel Gonçalves, Danilo Royer

摘要:

最近,Ott,Tomforde和Willis提出了一种新的方法来研究无限字母表上的单侧移位空间。在这种新方法中,有限型移位、边移位和M步移位的共轭类是不同的,作者猜想对每个非负整数M,存在一个与任何M步移位都不共轭的(M+1)步移位空间.在这篇短文中,我们建立了一类(M+1)步位移,不共轭的任何M步位移,从而证明他们的猜想是正确的。

英文摘要:

Recently Ott, Tomforde and Willis proposed a new approach for one sided shift spaces over infinite alphabets. In this new approach the conjugacy classes of shifts of finite type, edge shifts, and M-step shifts are distinct and the authors conjecture that for each non-negative integer M there exist an (M+1)-step shift space that is not conjugate to any M-step shift. In this short paper we build a class of (M+1)-step shifts that are not conjugate to any M-step shift and hence show that their conjecture is correct.
