摘要：
Real‐time evolution plays an important role to understand the dynamics of the early Universe. It would be of importance to be able to investigate such typical time dependent processes like particle production, reheating, creation and evolution of fluctuations, etc. In this paper we derive the one‐loop renormalized coupled einstein field equations of a scalar field with λϕ4 interaction in a classical curved space‐time of Friedmann‐Robertson‐Walker type. These equations can be used to calculate quantum corrections for the dynamics in the early Universe. Copyright © 1990 WILEY‐VCH Verlag GmbH & Co. KGaA
