* ABSTRACT
The diffusion of Brownian particles and the self-diffusion of fluid particles is studied by means of extensive molecular dynamics simulations of systems made of up to 32 000 two-dimensional disks interacting via a purely repulsive two-particle potential. The microscopic data are analyzed in terms of a generalized Langevin equation (GLE). Regions of normal and anomalous diffusion are identified and the respective scaling exponents are estimated by means of a generalized asymptotic Einstein relation.
