论文摘要
在本文中，我们研究了$ f（q）$重力的各向异性时空的精确解决方案，其中$ f \ weft（q \右）$是非金属标量表$ q $的任意功能。在这里，我们将特定的幂律形式视为$ f \ left（q \ right）=αq^{n+1}+β$，其中$α$，$β$和$ n $是免费的模型参数。使用幂律宇宙学（$ a \ left（t \ right）\ propto t^{m} $），分析宇宙学参数的物理行为，例如能量密度，压力，EOS参数，偏度参数。此外，我们通过能源条件验证了该模型，发现我们的$ f \ left（q \ right）$ \宇宙学模型的行为类似于当前的典型模型和将来$％λ$ cdm。
In this paper, we investigate the exact solution of an anisotropic space-time in the context of $f(Q)$ gravity, where $f\left( Q\right) $ is the arbitrary function of the non-metricity scalar $Q$. Here, we consider a specific power-law form as $f\left( Q\right) =αQ^{n+1}+β$, where $α$, $β$, and $n$ are free model parameters. Using power-law cosmology ($a\left( t\right) \propto t^{m}$), we analyze the physical behavior of cosmological parameters such as the energy density, pressure, EoS parameter, skewness parameter. Further, we validated the model with energy conditions and found that our $f\left( Q\right) $\ cosmological model behaves like the quintessence model in the present and $% Λ$CDM in the future.
