摘要：
We investigate λϕ4 theory within the Gaussian approximation in spatially flat Robertson‐Walker space in 3+1 dimensions. After having performed an adiabatic expansion for one of the ansatz functions we find that the renormalization of the energy‐momentum tensor provides two additional constraints which have to be satisfied by bare couplings. These conditions force the theory to be trivial after renormalization. Copyright © 1990 WILEY‐VCH Verlag GmbH & Co. KGaA
