摘要：

Exact solutions of the semi-classical Einstein equations with cosmological constant for conformally invariant free quantum fields in aa spatially flat Robertson-Walker metric are found when aa classical perfect fluid is present. The stability of the asymptotically Friedmann-de Sitter solutions is studied. The formers are found to be stable if alpha < 0, while the stability of the latter depends of the signs of alpha, beta, and LAMBDA.
