Abstract
It is shown that the standard treatment of lubrication effects in many-part icle hydrodynamic interactions leads to divergent three-particle contributi ons to the short-time translational self-diffusion coefficient. To resolve the problem the improved method to account for lubrication is proposed. The translational and rotational self-diffusion coefficients of the Brownian s emidilute suspension are then evaluated up to terms of the second order in volume fraction.
