A class of homogeneous scalar-tensor cosmologies with a radiation fluid

Abstract

We present a new class of exact homogeneous cosmological solutions with a radiation fluid for all scalar-tensor theories. The solutions belong to Bianchi type $V{I}_h$ cosmologies. Explicit examples of nonsingular homogeneous scalar-tensor cosmologies are also given.
