摘要：
We study the propagator of a massless minimally coupled scalar field in a power-law Robertson-Walker background. In the case where the energy-momentum density responsible for the formation of the background is provided by the scalar itself we find that the propagator shows no sign of singular infrared behavior for all values of the expansion parameter.
