Abstract

A new renormalization procedure for the solutions of Einstein's field equations in d dimensions obtainable by the inverse scattering method (ISM) of Belinskii and Zakharov [Sov. Phys. JETP 48, 985 (1978)] is presented. It allows one to obtain families of diagonal metrics which, in addition to the solitonic parameters that characterize the ISM, depend on 2(d - 3) extra arbitrary parameters. An example of cosmological relevance where the source is a massless scalar field in five dimensions is presented. It represents a general family of two-parameter four-dimensional metrics that for great times go into the perfect fluid Friedman-Robertson-Walker regime. © 1987 American Institute of Physics.
