In this work we study the longtime dynamics of concentratedhardsphere colloidal suspensions by Stokesian Dynamicscomputer simulations. In the study we emphasize the dependence of the selfdiffusion coefficient on the volume fraction as the systems approach the glass transition. Results are presented for other transport properties, including the velocity and stress autocorrelation functions. We compareour results with available experimental data and theoretical predictions, and with computer simulations without hydrodynamic interactions.
