Abstract
In this paper, we study 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 obtain 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 parameter are determined and their significant roles are discussed in respect of cosmic evolution of the universe. We observe that the model is consistent with modern cosmological observational data.
