Generating $G_2$--cosmologies with perfect fluid in dilaton gravity

General Relativity and Quantum Cosmology 2009-11-10 v1

Abstract

We present a method for generating exact diagonal G2G_2-cosmological solutions in dilaton gravity coupled to a radiation perfect fluid and with a cosmological potential of a special type. The method is based on the symmetry group of the system of G2G_2-field equations. Several new classes of explicit exact inhomogeneous perfect fluid scalar-tensor cosmologies are presented.
