The anisotropic distribution of the dark energy within the scope of LRS Bianchi type I model

Abstract

© 2018, Springer Science+Business Media B.V., part of Springer Nature. We investigate the anisotropic locally rotationally symmetric (LRS) Bianchi type I cosmological model with dark matter and anisotropic dark energy. We assume that the shear scalar (σ) is proportional to expansion scalar (θ). A special law is introduced for two skewness parameters that describe the deviation of pressure from isotropy. This law can lead to models: the hybrid expansion, the big rip and the little rip. The behavior of the Universe is discussed depending on the numerical parameters of the models.
