论文摘要
通过在当前宇宙学场景的极限内进行适当考虑的合理宇宙学假设，我们在Lyra歧管的框架内分析了5D设置的球面对称度量。预测模型宇宙是由真空能源主导的DE模型。该模型代表了一个振荡的模型，每个周期都以大爆炸的形式演变，并以大的紧缩结束，经历了一系列弹跳。宇宙是各向同性的，并且经历超指数的扩展。哈勃参数的值测量为$ h = 67.0691 $，非常接近$ h_0 = 67.36 \ pm0.54kms^{ - 1} mpc^{ - 1} $，由最新的Planck 2018结果估计的值。关于获得的宇宙学参数的详细讨论也显示了图。
With due consideration of reasonable cosmological assumptions within the limit of the present cosmological scenario, we have analysed a spherically symmetric metric in 5D setting within the framework of Lyra manifold. The model universe is predicted to be a DE model, dominated by vacuum energy. The model represents an oscillating model, each cycle evolving with a big bang and ending at a big crunch, undergoing a series of bounces. The universe is isotropic and undergoes super-exponential expansion. The value of Hubble's parameter is measured to be $H=67.0691$ which is very close to $H_0=67.36\pm0.54kms^{-1}Mpc^{-1}$, the value estimated by the latest Planck 2018 result. A detailed discussion on the cosmological parameters obtained is also presented with graphs.
