$p$ -自动序列作为线性元胞自动机列的一个刻画

A characterization of $p$-automatic sequences as columns of linear cellular automata

Eric Rowland, Reem Yassawi

摘要:

我们证明,具有特征$\mathbb F_q$的有限域$\mathbb F_q$上的序列是$p$ -自动的,当且仅当它作为时空图的一列出现,最终具有周期性初始条件,具有在$\mathbb F_q$上的记忆的线性元胞自动机。因此,由长度- $p$替换生成的子移位可以实现为线性元胞自动机的拓扑因子。

英文摘要:

We show that a sequence over a finite field $\mathbb F_q$ of characteristic $p$ is $p$-automatic if and only if it occurs as a column of the spacetime diagram, with eventually periodic initial conditions, of a linear cellular automaton with memory over $\mathbb F_q$. As a consequence, the subshift generated by a length-$p$ substitution can be realized as a topological factor of a linear cellular automaton.
