Stability of FRW universe inspired by modified entropy

Abstract

In the framework of modified entropy (Kaniadakis entropy) inspired cosmology, the phase space analysis is being analyzed by assuming several choices of linear and non-linear interaction terms between dark matter and dark energy. Interaction models provide a framework for studying and analyzing the behavior of complex systems. For this purpose, we develop dynamical systems and find the corresponding critical points in quintessence, phantom and ΛCDM phases. We are successful in finding the stable points which exhibit the attractive behavior in most of cases of interaction terms at quintessence, phantom and ΛCDM phases.
