G. P. Singh, Binaya K. Bishi

摘要:

本文在f(R,T)引力的背景下研究Bianchi I型宇宙。在有宇宙学常数存在的情况下,f(R,T)引力中的爱因斯坦场方程已被求解。和二次状态方程。本文讨论了两类f(R,T)引力,即f(R,T)= R + 2f(T)和f(R,T)= f_1(R)+ f_2(T)。基于这种合理的关系,我们考虑了一组模型。并对模型的一些物理和运动学性质进行了研究。

英文摘要:

This article deals with the study of Bianchi type-I universe in the context of f(R,T) gravity. Einstein's field equations in f(R,T) gravity has been solved in presence of cosmological constant ? and quadratic equation of state. Here we have discussed two classes of f(R,T) gravity i.e. f(R,T) = R + 2f(T) and f(R,T) = f_1(R) + f_2(T). A set of models has been taken into consideration based on the plausible relation. Also we have studied the some physical and kinematical properties of the models.
