Abstract : In a previous paper, the usual low-density expansion applicable to a Boltzmann gas was carried out, using a multiple time and space scale technique, to yield an expression for the lowest order two-particle correlation function on the scale of the collision time and the mean free path. In the present paper this technique was extended by introducing streaming operators which are generalizations of the operators first used by Bogoliubov and which allow higher order corrections in epsilon to the correlation functions to be obtained. The new result which this technique yields is the appearance of correction terms which are logarithmic in the density. (Author)
