A Symmetry Property of Christoffel Words
arXiv:2406.16408 · doi:10.4204/EPTCS.403.26
Abstract
Motivated by the theory of trapezoidal words, whose sequences of cardinality of factors by length are symmetric, we introduce a bivariate variant of this symmetry. We show that this symmetry characterizes Christoffel words, and establish other related results.
