Stability analysis for a cosmologically viable model of $f(R)$ gravity

Abstract

In recent times, there has been an increasing interest with theories of modified gravity as a means to gain a deeper understanding of the universe's late-time acceleration phase. In this study we focused our attention on a specific cosmologically viable $f(R)$ model. We performed a dynamic stability analysis of this model, revealing that the model supports presence of just one asymptotically stable solution which can explain the present-day acceleration of the universe.
