On considère les endomorphismes d’un monoïde défini par un système de réécriture spécial confluent qui admettent une extension continue à sa complétion donnée par les mots infinis réduits, et on étudie d’un point de vue dynamique la nature de leurs points périodiques infinis. Pour les endomorphismes préfixe-convergents et les endomorphismes expansifs, on détermine la structure de l’ensemble de tous les points périodiques infinis en termes de valeurs d’adhérence, on borne les périodes et on prouve que tous les points périodiques réguliers sont des attracteurs.

We consider endomorphisms of a monoid defined by a special confluent rewriting system that admit a continuous extension to the completion given by reduced infinite words, and study from a dynamical viewpoint the nature of their infinite periodic points. For prefix-convergent endomorphisms and expanding endomorphisms, we determine the structure of the set of all infinite periodic points in terms of adherence values, bound the periods and show that all regular periodic points are attractors.
