BIANCHI TYPE-V BULK VISCOUS UNIVERSE WITH CONSTANT DECELERATION PARAMETER

Abstract

In this article, we have obtained some exact solutions of the Einstein field equations with time-varying in existence of bulk viscosity in Bianchi type-V cosmological models. We have taken cosmic matter which follows a bar tropic equation of state. We see that the role of deceleration parameter $(q)$ is important to describe the different phases of the universe. Finally, we conclude that universe decelerates due to positive value of q while universe accelerates due to negative value of $q$. Some physical properties and behaviors of parameters on the solutions of field equations are discussed in this paper.
