Abstract
The generating functional for many-time correlation functions for a dilute gas is shown to satisfy the nonlinear Boltzmann equation for space and time scales large compared to corresponding molecular dimensions. The result is used to investigate the behavior of triplet space and time correlation functions. Corrections to the Markovian approximation are found, due to coupling of solutions to the linearized kinetic equation by the nonlinear Boltzmann operator.Keywords
