Abstract

In this paper we consider chameleonic generalized Brans-Dicke cosmology in the framework of Kantwoski-Sacks universes. We investigate the time dependence of the Brans-Dicke parameter ω(t) for an expanding Universe, and obtain an explicit dependence of ω(t) in different expansion phases of the Universe. Here we take the power law form of the scale factor. The behaviour of ω(t) is studied for matter-dominated, vacuum-energy-dominated universe, radiation-dominated and mass-less scalar-field-dominated era. It is also proposed to study the nature of the deceleration parameter.
