Cosmic evolution in $f(Q,T)$ gravity: Exploring a higher-order time-dependent function of deceleration parameter with observational constraints

Madhur Khurana, Himanshu Chaudhary, Saadia Mumtaz +2

In this research paper, we explore a well-motivated parametrization of the time-dependent deceleration parameter, characterized by a cubic form, within the context of late time cos…
