    Sturm Numbers and Substitution Invariance of 3iet Words

  • Original language description

    In this paper, we give a necessary condition for an infinite word defined by a non-degenerate interval exchange on three intervals (3iet word) to be invariant by a substitution: a natural parameter associated to this word must be a Sturm number. We deduce some algebraic consequences from this condition concerning the incidence matrix of the associated substitution. As a by-product of our proof, we give a combinatorial characterization of 3iet words.

    Sturmovská čísla a invariance na substituci 3iet slov

  • Czech description

    Prezentujeme nutnou podmínku pro to, aby nekonečné slovo definované nedegenerovanou výměnou 3 intervalů bylo invariantní na substituci: parametr přiřazený výměně intervalů musí být sturmovské číslo. Prezentujeme rovněž některé algebraické důsledky této podmínky týkající se incidenční matice dané substituce. Uvádíme také kombinatorickou charakterizaci 3iet slov.
