Massless scalar field in Robertson-Walker space-time

Research output: Contribution to journalLetter

Recently, exact spatially-homogeneous solutions have been found for a conformally invariant massless scalar field S(t) coupled to a Robertson-Walker geometry. We investigate extending these solutions to inhomogeneous scalar fields S(t, xl). For an isotropic scalar field S(t, r) we find a solution satisfying three of the five field equations. If we use REDUCE, we show that the remaining equations force S=S(t).
