Nous considérons une modèle apériodique de vent dans des arbres et nous montrons que, pour une configuration générique (dans le sens de Baire), la dynamique de vent–arbre est ergodique dans presque toutes les directions.

We consider aperiodic wind–tree models, and show that, for a generic (in the sense of Baire) configuration, the wind–tree dynamics is ergodic in almost every direction.
