Nonlinear dynamics of kinetic fluctuations and quasi-linear relaxation in plasma

We propose an approximation of pair correlations for solving the equations kinetic theory long-wave (or large-scale) fluctuations in gaseous media. The basic ones are general nonlinear large-scale at stage system evolution, derived from first principles statistical mechanics. show that based on kinetics case weak interaction between particles, it is possible to reproduce main results quasi-linear plasma. Thus, well-known plasma provided with a first-principle justification.
