子移位半群

摘要：

给定一个有限字母表上的单侧子移位$X$，我们考虑半群$S_X =L_X \cup \{0\}$，其中$L_X $是$X $的语言，当允许时，配备由级联给出的乘法运算，否则设置为消失。然后，我们研究的逆壳$H(S_X )$，它与C* 代数，已在文献中讨论了与子移位。

英文摘要：

Given a one-sided subshift $X$ on a finite alphabet, we consider the semigroup $S_X =L_X \cup \{0\}$, where $L_X $ is the language of $X $, equipped with the multiplication operation given by concatenation, when allowed, and set to vanish otherwise. We then study the inverse hull $H(S_X )$, relating it with C*-algebras that have been discussed in the literature in association with subshifts.
