A characterization of binary morphisms generating Lyndon infinite words (2105.01327v1)

Published 4 May 2021 in cs.DM

Abstract: An infinite word is an infinite Lyndon word if it is smaller, with respect to the lexicographic order, than all its proper suffixes, or equivalently if it has infinitely many finite Lyndon words as prefixes. A characterization of binary endomorphisms generating Lyndon infinite words is provided.
