| Popis: | 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) =\alpha +\beta \log \left( Q\right) $, where $\alpha $ and $\beta $ are free model parameters. In this study, we consider a parametrization of the Hubble parameter as $H\left( z\right) =\eta \left[ (z+1)^{-\gamma }+1\right] $, where $\gamma $ and $\eta $ 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 Comment: CQG accepted version |
