N2 - The oscillation of a classical field causes particle production, which then influences the evolution of the early universe. We examine this problem by solving a coupled system of Einstein-Boltzmann equations. In particular, particle production, caused by a damped oscillation of the extra space just prior to the compactification in vacuum Kaluza-Klein cosmology, leads to a period governed by an expansion law, with scale factor ∞ time.
