We have carried out a molecular-dynamics simulation of a two-dimensonal Lennard-Jones liquid near the triple point. We have compared some of the static- and dynamic-correlation functions with those of hard disks to study the effect of potential and with those of a three-dimensional triple-point Lennard-Jones liquid to study the effect of dimensionality. It is noted that while the behavior is qualitatively similar, there are distinct potential and dimensionality differences.
