Abstract: Kinetic description of the vacuum creation of the electron-positron plasma under action of the strong electromagnetic fields is considered in two simplest approximations. The results are compared with the numerical solution of the relevant kinetic equation. It allows to select the regions of effectiveness of the introduced methods and to analyse some features of the obtained analytical solutions.

Keywords: dynamic Schwinger effect, electron-positron pairs, relativistic kinetic equation, low-density approximation.
