Sturmian序列的Hankel行列式

Hankel determinants of a Sturmian sequence

Haocong Song, Wen Wu

摘要:

令$τ$为字母表$\{0,1\}$上的替换$1\to 101$和$0\to 1$。以1为前导的$τ$的不动点,记作$\mathbf{s}$,是一个Sturmian序列。我们首先用$f$ -表示给出了$\mathbf{s}$的一个特征。然后,我们证明了零的分布在行列式诱导整数格的第一象限的分区。结合这些性质,我们给出了所有$m\ge 0$和$n\ge 1$的Hankel行列式$H_{m,n}$和$\mathbf{s}$的显式值.

英文摘要:

Let $τ$ be the substitution $1\to 101$ and $0\to 1$ on the alphabet $\{0,1\}$. The fixed point of $τ$ leading by 1, denoted by $\mathbf{s}$, is a Sturmian sequence. We first give a characterization of $\mathbf{s}$ using $f$-representation. Then we show that the distribution of zeros in the determinants induces a partition of integer lattices in the first quadrant. Combining those properties, we give the explicit values of the Hankel determinants $H_{m,n}$ of $\mathbf{s}$ for all $m\ge 0$ and $n\ge 1$.
