Abstract

With the help of Nordtvedt's scalar tensor theory an exact analytic model of a non-minimally coupled scalar field cosmology in which the gravitational coupling G and the Hubble factor H oscillate during the radiation era is presented. A key feature is that the oscillations are confined to the early stages of the radiation dominated era with G approaching its present constant value while H becoming a monotonically decreasing function of time. The Brans Dicke parameter ω is chosen to be a function of Brans Dicke scalar field so that no conflict with observational constraints regarding its present value arises.
