摘要：
We have investigated LRS Bianchi type-I cosmological model in f(Q,T) theory of gravity with observational constraints. In f(Q,T) theory of gravity Q is non-metricity and T is a trace of energy-momentum tensor. Two different functional forms of f(Q,T) = AQ + BT and f(Q,T) = AQ(n) + BT are considered in this work where A, B and n 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 H(z), JLA, Pantheon, etc., by applying Root Mean Squared Error (RMSE) formula.
