论文摘要
In this paper, we investigate the homogeneous and isotropic flat FLRW Universe in the logarithmic form of $f\left( Q\right) $ gravity, where $% Q $ is the non-metricity scalar, specifically, $f\left( Q\right) =α+β\log \left( Q\right) $, where $α$ and $β$ are free model parameters.在这项研究中，我们将哈勃参数的参数化视为$ h \ left（z \ right）=η\ left [（z+1）^{ - γ} +1 \ right] $，其中$ r^{2} $ - r^{2} $ - test comply the $ r^{2} $ - test rastasts the the the the the the the nibe the nigh the nightble the nime ddatift y是$γ$和$γ$ and $γ$和$η$ $ 0.07 <z <2.36 $。此外，我们研究了模型的物理特性。我们分析能量条件以检查模型的兼容性。我们发现，由于现实是宇宙在加速阶段的现实，因此SEC被$ f \ left（q \右）的对数形式违反。最后，我们在这种情况下讨论了一些重要的宇宙学参数，以将我们的模型与诸如混蛋参数和状态基础参数之类的暗能量模型进行比较。
In this paper, we investigate the homogeneous and isotropic flat FLRW Universe in the logarithmic form of $f\left( Q\right) $ gravity, where $% Q $ is the non-metricity scalar, specifically, $f\left( Q\right) =α+β\log \left( Q\right) $, where $α$ and $β$ are free model parameters. In this study, we consider a parametrization of the Hubble parameter as $H\left( z\right) =η\left[ (z+1)^{-γ}+1\right] $, where $γ$ and $η$ are model/free parameters which are constrained by an $R^{2}$-test from 57 points of the Hubble datasets in the redshift range $0.07<z<2.36$. Further, we investigate the physical properties of the model. We analyze the energy conditions to check the compatibility of the model. We found the SEC is violated for the logarithmic form of $f\left( Q\right) $ gravity due to the reality that the Universe in an accelerating phase. Finally, we discuss some important cosmological parameters in this context to compare our model with dark energy models such as jerk parameter and statefinder parameters.
