摘要：
A new algorithm to generate families of inhomogeneous massless scalar field spacetimes is presented. New solutions to Einstein field equations, having a single isometry, are generated by breaking the homogeneity of massless scaler field G(2) models along one direction. As an illustration of the technique, spacetimes which in their late time limit represent perturbations in the form of gravitational and scalar waves propagating on a non-static inhomogeneous background are considered. Several features of the obtained metrics are discussed, such as their early and late time limits, structure of singularities and physical interpretation. [s0556-2821(99)09518-1].
