The general class of Bianchi cosmological models in f(R, T) gravity with dark energy in viscous cosmology

Abstract

The general class of Bianchi cosmological models in f(R, T) gravity with dark energy in the form of standard and modified Chaplygin gas and bulk viscosity have been considered. We have discussed three types of average scale factor by using a special law for deceleration parameter which is linear in time with negative slope. The model describes an accelerating universe for large value of time t, wherein the effective negative pressure induced by Chaplygin gas and bulk viscous pressure are driving the acceleration. © 2015, Indian Association for the Cultivation of Science.
