Abstract

Bianchi type-VI0 cosmological models of the universe filled with dark energy with constant and time-dependent equation of state parameters are investigated in general relativity We obtain exact solutions of Einstein s field equations using the condition that the shear scalar is proportional to the expansion scalar which represent singular and non-singular cosmological models of the universe The physical behavior of the models are discussed We conclude that the universe models do not approach isotropy through the evolution of the universe
