The EoS parameter was unfavorable inside the thawing zone and turned constructive inside the evolutionary case; having said that, the value in the EoS parameter stayed damaging inside the freezing area.

Discussion of the Results and Conclusions The SMHDE model was studied in this manuscript within the framework of CSMG theory even though taking into account the FRW universe. We studied the deceleration parameter, EoS, the square of sound speed, and also the power density as cosmological parameters. We predicted that the universe is in a decelerating and expanding phase known as de Sitter expansion. At a higher redshift, the graphical behavior depicted the decelerated phase q 0 and flipped over the accelerated phase for q 0. We concluded that deceleration parameter was identical in all three situations, and we propose that the conversion from deceleration to acceleration is coherent with those of [2,4,7,17,22,32,38,39]. It can be vital to note that the SMHDE model endorses a deceleration to acceleration transition that’s congruent with all the observational data. Various values of EoS, as an example = 0, 1 , 1, indicate that the universe is influenced by dust, 3 radiation, and stiff fluid, though ( = – 1 and -1 and -1) stand for quintessence, three CDM, and Phantom erases, respectively. Our findings demonstrated that the universe is being influenced by DE because the EoS anticipated accelerated expansion phases similar to those of [16,17,22]. The density parameter with the SMHDE model is nicely defined for all values of and 0. It truly is clear that the density parameter showed decreasing behavior and asymptotically converged to zero, implying that the cosmos approaches a De Sitter universe with eternally accelerated expansion. The square speed of sound was good for all parameter.
