| Abstract: | The relations between the kinetic equations with and without convolution in time are discussed on the basis of the kinetic equation for the Van Hove self-correlation function. Formal equivalence of both the equations is shown, and approximate scattering operators for the dilute-gas case and for the Brownian particle are considered. |
| Keywords: | Time correlation function non-Markovian kinetic equation distribution function collision integral memory function projection operator |
