Abstract
A simple model of classical diffusion on a random chain is studied. The velocities to the right and to the left are calculated. When one changes continuously the probability distribution of the hopping rates, a whole region is found where these two velocities vanish. In this region, the distance covered by a particle during the time behaves like , where depends continuously on . The exponent is calculated for a simple example.
