Scientific paper

The paper considers a number of explicitly soluble models of a massless, nonconformally-coupled scalar quantum field propagating in certain special Robertson-Walker background space-times. Regularization is effected using covariant point-splitting, and renormalized stress tensors are constructed according to the ansatz based on the DeWitt-Schwinger expansion. The results are all finite, conserved and free of regularization ambiguities. From these special cases it is possible to deduce a great deal about the structure of renormalized stress tensors in more general models in which computation-approximation techniques will be necessary.
