Frobenius数与自动序列

Frobenius Numbers and Automatic Sequences

Jeffrey Shallit

摘要:

具有$\gcd 1$的非负整数集合$S$的Frobenius数$g(S)$是不能表示为$S$的元素的线性组合的最大整数。给定序列${\bf s} = (s_i)_{i \geq 0}$,我们可以定义相关序列$G_{\bf s} (i) = g(\{ s_i,s_{i+1},\ldots \})$。在本文中,我们计算$G_{\bf s} (i)$的一些经典的自动序列:邪恶的号码,可憎的号码,和上下Wythoff序列。与通常的方法相比,我们的证明主要是基于自动机理论和逻辑。

英文摘要:

The Frobenius number $g(S)$ of a set $S$ of non-negative integers with $\gcd 1$ is the largest integer not expressible as a linear combination of elements of $S$. Given a sequence ${\bf s} = (s_i)_{i \geq 0}$, we can define the associated sequence $G_{\bf s} (i) = g(\{ s_i,s_{i+1},\ldots \})$. In this paper we compute $G_{\bf s} (i)$ for some classical automatic sequences: the evil numbers, the odious numbers, and the lower and upper Wythoff sequences. In contrast with the usual methods, our proofs are based largely on automata theory and logic.
