| Popis: | Anisotropic and spatially homogeneous Bianchi type-V space–time is considered in the presence of matter and anisotropic dark energy in Barber’s (Gen. Relativ. Gravit. 14, 117. (1982)) second self-creation theory of gravitation. An anisotropic modified holographic Ricci dark energy model is presented using linearly varying deceleration parameter (Akarsu and Dereli. Int. J. Theor. Phys. 51, 612 (2012)), energy density of modified holographic Ricci dark energy, and the relation between the metric potentials. Some physical and kinematical properties of the model are discussed graphically by choosing suitable values of the parameters, which are found to be in good agreement with modern cosmological observational data. |
