摘要
Using the cosmological data sets, accelerating cosmological models are obtained in this paper by constraining the free parameters in symmetric teleparallel gravity. Using the best-fit values of free parameters, we determine the present values of geometrical parameters and the late-time behaviour of the universe. We also consider two $f(Q)$ models ($Q$ being the non-metricity scalar): one that contains the term of higher power of non-metricity scalar and the other with the inverse. From the constrained free parameters, the present values of the geometrical parameters are obtained and that of the effective equation of state parameter for both models. Interestingly, we found that all the values lie within the range prescribed by the cosmological observations. Further, the models exhibit the $\Lambda{CDM}$ behaviour at the late time of the evolution.
