Chaplygin Gas Field Potential in f(R) Gravity

Abstract

In this paper, The Friedmann-Robertson-Walker (FRW) cosmological model with bulk viscosity is investigated in the f(R) theory of gravitation. For the Power, the field equations are solved. The functional form of the function f(R) such as f(R) = R^3/2 is chosen for investigation. We have discussed the deceleration parameter. We have considered a model of Chaplygin gas. Chaplygin gas field potential and scalar field are obtained. We study the behaviour of potential of Chaplygin gas model.
