Abstract
The evolution of reduced distribution functions is studied for an inhomogeneous dense classical fluid by methods previously used to study homogeneous fluids. So long as only short-range order is present in the fluid and the variation in properties caused by the inhomogeneity is negligible over distances of the order of the region of a collision, then the evolution equations for the one-particle and -particle distribution functions are obtained. They take a simple Markovian form if the one-particle distribution changes negligibly in times of the order of the duration of a collision. The operators involved in the evolution equations are studied. Their physical meaning and relationship to the classical Boltzmann equation are considered.
