广义Thue-Morse序列的阿贝尔复杂度

On the abelian complexity of generalized Thue-Morse sequences

Jin Chen, Zhi-Xiong Wen

摘要:

本文研究了广义Thue-Morse序列$\mathbf{t}^{(k)}$的阿贝尔复杂度$ρ_n^{ab}(\mathbf{t}^{(k)})$.对于每个整数$n\geq k$,我们得到了$ρ_n^{ab}(\mathbf{t}^{(k)})$的精确值。因此,$ρ_n^{ab}(\mathbf{t}^{(k)})$最终是周期性的,周期为$k$。此外,我们证明了一类无穷序列的阿贝尔复杂性是$k$ -自动的。

英文摘要:

In this paper, we study the abelian complexity $ρ_n^{ab}(\mathbf{t}^{(k)})$ of generalized Thue-Morse sequences $\mathbf{t}^{(k)}$. We obtain the exact value of $ρ_n^{ab}(\mathbf{t}^{(k)})$ for every integer $n\geq k$. Consequently, $ρ_n^{ab}(\mathbf{t}^{(k)})$ is ultimately periodic with the period $k$. Moreover, we show that the abelian complexities of a class of infinite sequences are $k$-automatic.
