| dc.description.abstract | The Vlasov kinetic equation for plasma that is usually treated as a collisionless approximation is shown to satisfy the complete BBGKY hierarchy after some modification of the latter, thus being an exact solution of it. Based on the perturbation method originated from this exact solution, linearized equations for averaged deflections of plasma particles from their unperturbed self-consistent trajectories are derived to be used for the investigation of plasma waves. Instead of the Maxwell equations for electromagnetic fields their solutions in the Lienard-Wiechert form are used. All the known results of the ordinary linear theory of plasma oscillations and waves are shown to be reproducable in this approach, but in addition, small corrections of the first order in the plasma parameter due to the Debye screening are obtained. A simple consideration of a rarefied plasma in a strong magnetic field is given indicating the possibility of a non-cyclotron character of the motion of the particles that may be important for the plasma confinements in magnetic traps | en_US |
