Reexamining RHDE Models in FRW Universe with two IR cut-off with redshift parametrization

Abstract

In this paper, we have investigated that the gravitational field equations are not compatible with conservation equation in Dixit et al. \textcolor{blue}{[Dixit et al. Euro. Phys. J. Plus \textbf{135}, 831 (2020)]}. Therefore, the expression for equation of state parameter along with the dynamics of ${\omega }_T$ - ${\omega }_T^{\prime }$ plane does not reflect the actual behaviors of RHDE models in $f(R,T)$ gravity and thus the method and technique given in Dixit et al. \textcolor{blue}{[Dixit et al. Euro. Phys. J. Plus \textbf{135}, 831 (2020)]} represents a fractured way for analyzing RHDE models in $f(R,T)$. We also investigate that the derived Universe is in decelerating phase of expansion for $0\le \beta \le 1.5$ which is contrary to the result obtained in above targeted paper.
