Nous considérons le processus de Lorentz dans le plan avec des obstacles convexes disposés de manière périodique (nous supposons de plus que l'horizon est fini). Dans ce modèle, une particule ponctuelle se déplace à vitesse unitaire et sa vitesse obéit à la loi de la réflexion de Descartes à l'instant d'un choc contre un obstacle. La scène aléatoire est donnée par une suite de variables aléatoires indépendantes de même loi, centrées, de variance finie non nulle. Chacune de ces variables aléatoires est associée à un obstacle. Nous associons à la particule une somme qui évolue avec le temps. Cette somme est nulle au départ. A chaque fois que la particule touche un obstacle, elle gagne la valeur de la variable aléatoire associée à cet obstacle. Nous montrons que la somme totale gagnée au temps
We consider the periodic planar Lorentz process with convex obstacles (and with finite horizon). In this model, a point particle moves freely with elastic reflection at the fixed convex obstacles. The random scenery is given by a sequence of independent, identically distributed, centered random variables with finite and non-null variance. To each obstacle, we associate one of these random variables. We suppose that each time the particle hits an obstacle, it wins the amount given by the random variable associated to the obstacle. We prove a convergence in distribution to a Wiener process for the total amount won by the particle (normalized by
