Abstract
  • For any in?finite word r over a, b we associate two infi?nite words min(r), max(r) such that any prefi?x of min(r) (max(r), respectively)? is the lexicographically smallest (great- est, respectively) among the factors of r of the same length. We prove that (min(r); max(r)) = (as; bs) for some infi?nite word s if and only if r is a proper Sturmian word or an ultimately peri- odic word of a particular form. This result is based on a lemma concerning sequences of infi?nite words. (literal)
