Abstract

In this paper the coefficients of the diffusion equation for a unidimensional mechanical system are calculated up to O(1/beta(7)), in termsof the frictional constant beta. This procedure is a variant of the one used previously, which is based on splitting the velocity into a deterministic plus a rapidly fluctuating part. This splitting was adjusted so as to make the memory integral, which appears in the expression for the diffusion coefficient, vanish. Consequently, the deterministicpart of the velocity results to satisfy a modified Hamilton-Jacobi dissipative equation in configuration space. Here, a new expansion of the response function is introduced, so as to make calculations more expeditious.
