Model parameters in the context of late time cosmic acceleration in $f(Q,T)$ gravity

Laxmipriya Pati,

Abstract: The dynamical aspects of some accelerating models are investigated in the framework of an extension of symmetric teleparllel gravity dubbed as f (Q, T ) gravity. In this gravity theory, the usual Ricci tensor in the geometrical action is replaced by a functional f (Q, T ) where Q is the non-metricity and T is the trace of the energy-momentum tensor. Two different functional forms are considered in the present work. In order to model the Universe, we have considered a signature flipping deceleration parameter s… Show more
