Description

Equation of State of the coupled dark energy can be expressed in terms of the ration of total pressure to the vacuum energy density. Here in this article the stability of the saddle points are produced for different types of functions which can be considered to produce the quintessence models. Chosen functions are further tested with CPL parameterization to fit them for dark energy models.
