The self-diffusion coefficient exhibits no detectable anomaly. The data for the shear viscosity and the mutual diffusion coefficient are fully consistent with the asymptotic power laws and amplitudes predicted by renormalization and by mode-coupling theories provided that finite-size effects and a noncrititical background contribution are suitably accounted for. This work resolves a controversy raised by other molecular simulations reported in the literature. Extended Abstract Status: Not Uploaded | ||
