Role of Chameleon Field in presence of Variable Modified Chaplygin gas in Brans-Dicke Theory
Abstract
In this work, we have considered FRW model of the universe for Brans-Dicke (BD) theory with BD scalar field as a Chameleon field. First we have transformed the field equations and conservation equation from Jordan's frame to Einstein's frame. We have shown in presence of variable modified Chaplygin gas, the potential function V and another analytic function f always increase with respect to BD-Chameleon scalar field φ.
