Dynamical study of interacting Ricci dark energy model using Chevallier-Polarsky-Lindertype parametrization

The main focus of this paper is to investigate an interacting phenomena between dark matter-dark energy within a non-flat FLRW spacetime geometry bounded by a horizon with specific Ricci cut-off. We assume an interaction term between two dark components of the fluid and evaluate it analytically via physical quantities like energy density and pressure. We constraint the model parameters and found specific region of validity for these parameters. Considering ‘Chevallier-Polarsky-Linder type parametrization’ of the coincidence parameter , we observed that our model possess a future singularity of Type III. After finding the singular behavior, we examine the nature of our model via cosmological parameters like . It is noted that our model is very close to cold dark matter (CDM) model.
