Scientific paper

We derive the unique, local vacuum stress tensor for electromagnetic,
neutrino and massless scalar fields propagating in a Robertson-Walker
background spacetime. The result is used to compute the numerical
coefficients of the conformal trace anomalies from the known values of
the Casimir energy in the Einstein universe.
