Onedimensional motion of collisionless particles in gasdynamic approximation
Abstract
It is shown that onedimensional collisionless degenerate motion of particles in a plasma coincides exactly with gasdynamical 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 selfconsistent solution more complicated due to potential calculations but the gasdynamical part remains the same. One application of the proposed method is the theory of galaxy formation.
