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.
Bianchi ii型修正了Barber自我创造引力理论中的全息利玛西暗能量模型
本文研究了Barber第二次自我创造引力理论中存在物质和修正全息Ricci暗能量的空间均匀和各向异性的Bianchi型时空。通过假设(i)平均哈勃参数有一个特殊的变化规律,(ii)剪切张量σi i的分量σ 11 1与模型中的展开标量成正比,我们得到了场方程的精确解。确定了一些物理和动力学参数,并讨论了它们在宇宙演化中的重要作用。我们观察到该模型与现代宇宙学观测数据是一致的。
