It is believed that kinematical characteristics of a group of stars, as the velocity dispersion or the lag in rotation, change systematically with time. This kinematical evolution is widely used for the determination of stellar ages. In particular, velocity dispersion should increase with time owing to irregular galactic force field. A classical formula for the increase of stellar velocity v with the age τ
