Abstract
Numerical results on the dynamics in a Lennard-Jones system close to the glass transition are presented, using a kinetic model presented in an earlier paper. The theory is based on the Zwanzig-Mori procedure for deriving formally exact transport equations combined with mode-coupling approximations. Results for a number of different dynamical quantities of experimental interest are presented and the model is shown to reproduce many of the characteristic features of a liquid-glass transition. Comparisons are made with available computer simulation data and analytical results for the same mode-coupling model.
