摘要

本文研究了f(R, T)引力框架下的LRS - Bianchi i型宇宙学模型,其中R为里奇标量,T为畴壁存在时的应力能量动量张量。我们利用Berman(1983)提出的哈勃参数的特殊变化规律,得到了与宇宙模型相对应的场方程的精确解。得到了宇宙的能量条件和物理行为,并利用一些物理参数和它们的图形讨论了它们的演化。此外,我们可以使用Statefinder参数来测试模型的有效性。

Energy Conditions and Statefinder Diagnostic of Cosmological Model with Special Law of Hubble Parameter in f(R, T) Gravity
In this article, we examine the LRS Bianchi type-I cosmological model in the framework of f(R, T) gravity, where R is the Ricci scalar and T is the stress energy momentum tensor in the presence of Domain wall. we used the special law of variation of Hubble’s parameter proposed by Berman (1983) to obtained the exact solution of field equation, corresponds to the model of the universe. The Energy conditions and physical behaviour of the universe has been obtained and their evolution has been discussed using some physical parameter and by means of their graphs. Also, we can use the Statefinder parameter for testing the validity of the model.
