摘要：

We investigate the dynamics generated by iterated maps and analyze the motion in terms of the probabilistic continuous-time Levy walk approach. We consider the case of particles which move randomly with a constant velocity between points of halt and study the mean-squared displacement [r2(t)] and the propagator P(r, t), the probability to be at location r at time t having started at the origin at t = 0. We emphasize the importance of the stationary state and demonstrate it in the case of enhanced diffusion.
