In this paper we consider the transition from the Kadanoff-Baym equations to the quantum kinetic equations and then to the Boltzmann equation in curved space-time. As one expects from general considerations, the derived equations appear to be covariant generalizations of the corresponding equations in Minkowski space-time. The formalism will be applied to test approximations commonly made in the computation of the baryon asymmetry in the leptogenesis scenario.
