One-dimensional motion of collisionless particles in gasdynamic approximation
Abstract
It is shown that one-dimensional collisionless degenerate motion of particles in a plasma coincides exactly with gas-dynamical motion before the occurrence of caustics. Gravitational or electric forces do not destroy this coincidence for any set of particles with definite mass and charge. These forces make the self-consistent solution more complicated due to potential calculations but the gas-dynamical part remains the same. One application of the proposed method is the theory of galaxy formation.
