LRS Bianchi type-I cosmological model in f(Q,T) theory of gravity with observational constraints

Abstract

We have investigated LRS Bianchi type-I cosmological model in [Formula: see text] theory of gravity with observational constraints. In [Formula: see text] theory of gravity [Formula: see text] is non-metricity and T is a trace of energy–momentum tensor. Two different functional forms of [Formula: see text] and [Formula: see text] are considered in this work where [Formula: see text], [Formula: see text] and [Formula: see text] are model parameters. We have obtained the best-fit values of constant parameters using least square method for observational constraints using the available datasets like Hubble dataset [Formula: see text], JLA, Pantheon, etc., by applying Root Mean Squared Error (RMSE) formula.
