| description | This paper aims to explore the evolution of the universe in the background of Palatini fR gravity. Considering Amendola Gannouji Polarski Tsujikawa (AGPT) fR gravity model, we perform a dynamical system analysis within the FLRW universe in order to analyze the impacts of this gravity model on large-scale structure and dynamics of universe. With the aid of fixed points and eigenvalues, stability properties are analyzed to study long term behavior of universe. For analyzing the feasibility of different phases of universe, the equation of state parameter ωeff was utilized. We found that for the fR model under consideration, the results correspond to both of the early as well as the late time epochs for the said fR model. |
