迭代伪随机闭包的不动点
On the fixed point of the iterated pseudopalindromic closure
摘要：
在Sturmian词的研究中首次引入了迭代回文闭合，最近将其推广到伪回文闭合。这个运算符允许我们构造出具有无限多个伪回文前缀的单词，称为伪标准单词。本文给出了迭代伪随机闭包下不动点的几个组合性质。
英文摘要：
First introduced in the study of the Sturmian words, the iterated palindromic closure was recently generalized to pseudopalindromes. This operator allows one to construct words with an infinity of pseudopalindromic prefixes, called pseudostandard words. We provide here several combinatorial properties of the fixed points under the iterated pseudopalindromic closure.
