Exploring the bouncing cosmological models in symmetric teleparallel gravity

Abstract

In this study, the bouncing cosmological models have been presented in the non-metricity-based gravitational theory, the [Formula: see text] gravity, where [Formula: see text] be the non-metricity scalar. The two bouncing cosmological models, one in which the Lagrangian [Formula: see text] is assumed to have a linear dependence on [Formula: see text] and the other in which it has a polynomial functional form have been shown. It has been obtained that the parameters of the models largely depend on the behavior of the models. The equation of state (EoS) parameter shows the bouncing behavior of the Universe. It should be highlighted that the built-in cosmological models go against the energy requirements. The kinematical and physical characteristics of the models are also analyzed.
