The stochastic-differential-equation approach to dynamical problems of dense fluids is presented. The stochastic Boltzmann-Enskog equation is derived from the Liouville equation of a classical hard sphere system. By the method of the Chapman-Enskog expansion, it is shown that the equation reduces near the local equilibrium to the equations of fluctuations in fluids of Landau and Lifshitz. Discussions are given on the possibility of using the Landau-Lifshitz formula as a microscopic expression of transport coefficients.
