Infinite Smooth Lyndon Words

Abstract:
In a recent paper, Brlek et al. showed that some extremal infinite smooth words are also infinite Lyndon words. This result raises a natural question: what are the infinite smooth words that are also infinite Lyndon words? In this paper, we give the answer: the only infinite smooth Lyndon words are m{a < b}, with a, b even, and m{1 < b}, with b odd, where mA is the minimal infinite smooth word with respect to lexicographic order over the numerical alphabet A.
