Cosmological Model with Modified Chaplygin Gas and Dissipative Effects

Abstract

A study of cosmological solutions in the presence of Modified Chaplygin gas(MCG) with dissipative term described by Eckart, truncated and full causaltheories proposed by Israel and Stewart for a flat homogeneous isotropicFriedman-Robertson walker spacetime are given here. The interesting featureof the models is that it admits present acceleration phase as well as earlyinflationary phase with intermediate past deceleration phase of the evolutionof the universe. The models may also help to predict future evolution of theuniverse. Statefinder diagnostic is also performed for the Eckart, truncatedand full causal theories
