| Abstract: | Methods developed in the kinetics for plasma physics are used for the investigation of the perturbation in homogeneous collisionless self-gravitation systems of degenerate particles. The dispersion relation of small oscilations in memtioned systems is derived,and the formulae are given for calculation of the damping time and the collapse time. |
