论文摘要
在$ f（r，t）$重重中探索了飞机对称的比安奇-i型号，其中$ r $是ricci标量，$ t $是能量巨头张量的痕迹。考虑到特定的哈勃参数，该参数获得了恒定减速参数。各种进化阶段是在获得物理可行宇宙学场景的约束下确定的。尽管采用了一个（主要）物质源，但由于物质和$ f（r，t）$重力之间的耦合，出现了一个附加物质源，它模仿了完美的液体或异国情调。解决方案也扩展到标量场模型的情况。模型的运动学行为仍然独立于$ f（r，t）$重力。有效物质的身体行为也与一般相对论相同。发现$ f（r，t）$重力可以作为暗示候选者的一个很好的选择，以描述当前宇宙的加速膨胀。
A plane symmetric Bianchi-I model is explored in $f(R,T)$ gravity, where $R$ is the Ricci scalar and $T$ is the trace of energy-momentum tensor. The solutions are obtained with the consideration of a specific Hubble parameter which yields a constant deceleration parameter. The various evolutionary phases are identified under the constraints obtained for physically viable cosmological scenarios. Although a single (primary) matter source is taken, due to the coupling between matter and $f(R,T)$ gravity, an additional matter source appears, which mimics a perfect fluid or exotic matter. The solutions are also extended to the case of a scalar field model. The kinematical behavior of the model remains independent of $f(R,T)$ gravity. The physical behavior of the effective matter also remains the same as in general relativity. It is found that $f(R,T)$ gravity can be a good alternative to the hypothetical candidates of dark energy to describe the present accelerating expansion of the universe.
