Abstract

For a rescaled linear one-dimensional transport equation with spatial dependence describing the evolution of the electron distribution in a weakly ionized host medium under the influence of a constant electric field, we derive recursively the n-th term in the Hilbert expansion and prove that the n-th order Hilbert expansion provides an (n + 1)-th order approximation of the electron distribution function and the drift velocity under certain initial conditions. The proof is based on the perturbation formula for the mild solution of the initial-value problem and an existence result for stationary solutions in a weighted L1-space.
