abstract = {It has been recently shown that the velocity
autocorrelation function of a tracer particle immersed in a
simple liquid scales approximately with the inverse of its
mass. With increasing mass the amplitude is systematically
reduced and the velocity autocorrelation function tends to a
slowly decaying exponential, which is characteristic for
Brownian motion. We give here an analytical proof for this
behavior and comment on the usual explanation for Brownian
dynamics which is based on the assumption that the memory
function is proportional to a Dirac distribution. We also
derive conditions for Brownian dynamics of a tracer particle
which are entirely based on properties of its memory
function.},
