Abstract

Spatially homogeneous, anisotropic Bianchi types I-II-III-V-VIo-VIh and Kantowski-Sachs (KS) are shown to have perfect fluid solutions in Jordan-Brans-Dicke (JDB) cosmological theory. All the solutions obey the relation ɛψ=aη2+bη+c, where ɛ and ψ are the re-scaled energy density and the re-scaled scalar field, respectively, and η is a ‘time parameter’. This relation is derived in Bianchi type-I and gives rise to the general solution for this model universe. In the remaining Bianchi types this same relation is shown to hold as well; and new solution, some of which do not possess locally rotational symmetry, are obtained.
