Thue-Morse词的排列复杂性

Permutation Complexity of the Thue-Morse Word

Steven Widmer

摘要:

给定一个可数集X(通常取为自然数或整数),X的一个无限置换π是X的一个线性序。本文研究了与Thue-Morse字相关的自然数上的无穷置换的组合复杂性。通过研究子排列中的模式和Thue-Morse态射对子排列的作用,建立了复杂度的计算公式。

英文摘要:

Given a countable set X (usually taken to be the natural numbers or the integers), an infinite permutation πof X is a linear ordering of X. This paper investigates the combinatorial complexity of the infinite permutation on the natural numbers associated with the well-known and well-studied Thue-Morse word. A formula for the complexity is established by studying patterns in subpermutations and the action of the Thue-Morse morphism on the subpermutations.
