Abstract
Abstract In this article, we examined the Starobinsky gravity model in homogeneous and isotropic space-time described by the Friedman-Robertson-Walker metric. In the framework of this model, cosmological parameters were described that explain it in the early and late evolutionary times, such as the slow roll parameters, perturbation of curvature, scalar-tensor ratio, equation of state parameter and deceleration parameter. For reconstruction, an ansatz of a special type was chosen, which can be considered as a generalization of the Chaplygin type of gas. Energy conditions are also calculated for this model. Dependencies of these parameters on cosmological time are plotted graphically.
