Anisotropic Bianchi type-II modified holographic Ricci dark energy model in scale-covariant theory of gravitation

Abstract

In this paper, we obtain an anisotropic Bianchi type-II space–time with dark matter and modified holographic Ricci dark energy in the scale-covariant theory of gravitation. Exact solutions of the field equations are obtained by assuming (i) a negative constant value of the deceleration parameter, (ii) the component [Formula: see text] of the shear tensor [Formula: see text] is proportional to the mean Hubble parameter, and (iii) the gauge function [Formula: see text] is proportional to a power function of the average scale factor. We have also discussed some important physical aspects of the model, which is in agreement with the modern cosmological observations.
