Hankel determinants of a Sturmian sequence

Combinatorics 2020-07-21 v1

Abstract

Let τ\tau be the substitution 11011\to 101 and 010\to 1 on the alphabet {0,1}\{0,1\}. The fixed point of τ\tau leading by 1, denoted by s\mathbf{s}, is a Sturmian sequence. We first give a characterization of s\mathbf{s} using ff-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 Hm,nH_{m,n} of s\mathbf{s} for all m0m\ge 0 and n1n\ge 1.
