Résumé
Abstract

Soit $x = x_{0} x_{1} \dots$ un point fixe de la substitution sur l’alphabet $\{a, b\},$ et soit $U_{a} = (\begin{matrix} - 1 & - 1 \\ 0 & 1 \end{matrix})$ et $U_{b} = (\begin{matrix} 1 & 1 \\ 0 & 1 \end{matrix})$ . On donne une classification complète des substitutions $σ : {\{a, b\}}^{☆}$ selon que la suite de matrices ${(U_{x_{0}} U_{x_{1}} \dots U_{x_{n}})}_{n = 0}^{\infty}$ est bornée ou non. Cela correspond au fait que les chemins orientés engendrés par les substitutions sont bornés ou non.

Let $x = x_{0} x_{1} \dots$ be a fixed point of a substitution on the alphabet $\{a, b\},$ and let $U_{a} = (\begin{matrix} - 1 & - 1 \\ 0 & 1 \end{matrix})$ and $U_{b} = (\begin{matrix} 1 & 1 \\ 0 & 1 \end{matrix})$ . We give a complete classification of the substitutions $σ : {\{a, b\}}^{☆}$ according to whether the sequence of matrices ${(U_{x_{0}} U_{x_{1}} \dots U_{x_{n}})}_{n = 0}^{\infty}$ is bounded or unbounded. This corresponds to the boundedness or unboundedness of the oriented walks generated by the substitutions.
