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

@article{Pati2021ModelPI, title={Model parameters in the context of late time cosmic acceleration in f(Q,T) gravity}, author={Laxmipriya Pati and B. Mishra and S. K. Tripathy}, journal={Physica Scripta}, year={2021}, volume={96} }

The dynamical aspects of some accelerating models are investigated in the framework of an extension of symmetric teleparallel 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…
