We investigate the dynamics generated by iterated maps and analyze the
motion in terms of the probabilistic continuous-time Levy walk approa
ch. We consider the case of particles which move randomly with a const
ant velocity between points of halt and study the mean-squared displac
ement [r2(t)] and the propagator P(r, t), the probability to be at loc
ation 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.
