Introduction

The theory of Brownian motion in an homogeneous fluid is discussed with in the framework of the method for the construction of the distribution function for a nonequilibrium system.

Hamiltonian

We consider in the framework of classical mechanics the system of Brownian particles and fluid with the Hamiltonian

<math>\mathcal{H} = \mathcal{H}_1 + \mathcal{H}_2</math>

with

<math>\mathcal{H}_1 = \sum_\alpha \left[ \frac{\mathbf{P}_\alpha^2}{2M} + \sum_q V(|\mathbf{R}_\alpha-\mathbf{r}_q|) \right]</math>

and

<math>\mathcal{H}_2 = \sum_i \left[ \frac{\mathbf{p}_i^2}{2m} + \sum_{f(<i)} V(|\mathbf{r}_i-\mathbf{r}_j|) \right]</math>

where<math>\mathbf{P}_\alpha</math>, <math>\mathbf{R}_\alpha</math>, <math>M</math>, <math>\mathbf{p}_i</math>, <math>\mathbf{r}_i</math> and <math>m</math> and the momentum, position and mass of the <math>\alpha</math>-th Brownian particle and the <math>i</math>-th fluid particle respectively; <math>V(|\mathbf{R}_\alpha-\mathbf{r}_i|)</math> is the interaction potential of the Brownian particle with the fluid particle; <math>u(|\mathbf{r}_i-\mathbf{r}_j|)</math> is the interaction energy of two fluid particles.
