Brans-Dicke Cosmology in an anisotropic model when Velocity of Light Varies
Subenoy Chakraborty, N. C. Chakraborty, Ujjal Debnath
Abstract
In this paper, we have studied Brans-Dicke Cosmology in anisotropic Kantowski-Sachs space-time model; considering variation of the velocity of light. We have addressed the flatness problem considering both the cases namely, (i) when the Brans-Dicke scale field ϕ is constant (ii) when ϕ varies, specially for radiation dominated era perturbatively and non-perturbatively and asymptotic behaviour have been studied.
