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.
