摘要

在本研究中，我们重点研究了在充满湿暗流体作为候选暗能量的引力 f(R) 理论框架内的 LRS 比安奇 -I 型度量。该度量的解是一个加速宇宙，它是通过假设负的恒定减速参数并利用幂律关系推导出来的。此外，我们还通过图表直观地分析了该公因子的动力学和几何特性。

Accelerating universe with wet dark fluid in modified theory of gravity

In the present work we have focused on the investigation of LRS Bianchi type –I metric within the framework of $f (R)$ theory of gravity filled with wet dark fluid as the candidate of dark energy. The solution of the metric is an accelerating universe, derived by assuming the negative constant deceleration parameter and utilizing a power law relation. Additionally, we have visually analyzed the metric's dynamical and geometrical properties through graphical representations.
