The Einstein equation in D dimensions, if restricted to the class of space-times possessing n = D−2 commuting hypersurface–orthogonal Killing vectors, can be equivalently written as metric-dilaton gravity in 2 dimensions with n scalar fields. For n = 2, this results reduces to the known reduction of certain 4-dimensional metrics which include gravitational waves. Here, we give such a representa...

I present here a new algorithm to generate families of inhomogeneous mass-less scalar field cosmologies. New spacetimes, having a single isometry, are generated by breaking the homogeneity of massless scalar field G 2 models along one direction. As an illustration of the technique I construct cosmo-logical models which in their late time limit represent perturbations in the form of gravitationa...
