Bianchi type II modified holographic Ricci dark energy model in Barber’s self-creation theory of gravitation

Abstract

In this paper, we studied a spatially homogeneous and anisotropic Bianchi type II space-time in the presence of matter and modified holographic Ricci dark energy in Barber’s second self-creation theory of gravitation. We obtained exact solution of the field equations by assuming (i) a special law of variation of the mean Hubble parameter and (ii) the component σ1 1 of the shear tensor σi i is proportional to the expansion scalar in the model. Some physical and dynamical parameters were determined and their significant roles are discussed with respect to cosmic evolution of the universe. We observe that the model is consistent with modern cosmological observational data. © 2022, Canadian Science Publishing. All rights reserved.
