Vlasov kinetic equation
where is the particle distribution function, while the index is indicative for the kind of particle. The self-consistent electro-magnetic field follows from the Maxwell equations
in which the volume density of electric charge and the volume density of electric current are related to the particle distribution function via
Vlasov's kinetic equation may be obtained from the Liouville equation for a distribution function of all particles of a given kind if either the particle interactions are neglected or it is assumed that the multi-particle distribution function is the product of single-particle distribution functions , .
The system of equations (1), (2), (3), proposed by A.A. Vlasov, is extensively employed in plasma physics. The linear theory, based on linearization of equations (1), (2), (3), is the most fully developed. It is used in the study of small oscillations and the stability of a plasma . The quasi-linear theory, which makes it possible to study non-linear effects, is in full development.
