论文摘要
在F（r，t）重力理论中当前宇宙学观测值的范围内，我们在5D设置中分析了球形对称时空。考虑到合理的宇宙学假设以获得精确的解决方案，对场方程进行了仔细的研究。我们已经获得了经历超指定扩展的各向同性模型宇宙。据预测，模型宇宙的行为就像暗能量（真空能）模型。在当前情况下，模型以缓慢而均匀的形状变化发展。据观察，宇宙靠近或几乎平坦。该模型没有初始奇异性，预计将在有限的时间内接近以真空能量或宇宙学常数为主导的开发阶段。鉴于最近的研究获得了有关宇宙学参数的全面讨论，并详细介绍了图。
Within the limits of the present cosmological observations in f(R,T) gravity theory, we have analyzed a spherically symmetric space-time in 5D setting. The field equations have been carefully studied considering reasonable cosmological assumptions to obtain exact solutions. We have obtained an isotropic model universe undergoing super-exponential expansion. It is predicted that the model universe behaves like a dark energy (vacuum energy) model. In the present scenario, the model evolves with a slow and uniform change of shape. It is observed that the universe is close to or nearly flat. The model is free from initial singularity and is predicted to approach the de-Sitter phase dominated by vacuum energy or cosmological constant in the finite-time future. A comprehensive discussion on the cosmological parameters obtained in view of the recent studies is presented in detail with graphs.
