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 ωT\omega_{T} - ωT\omega_{T}^{\prime} plane does not reflect the actual behaviors of RHDE models in f(R,T)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)f(R,T). We also investigate that the derived Universe is in decelerating phase of expansion for 0β1.50 \leq \beta \leq 1.5 which is contrary to the result obtained in above targeted paper.
