Dynamical Analysis of the Dirac-Born-Infeld type of Tachyon field minimally coupled with barotropic fluid using EOS parametrization of a field

Abstract

In this paper, we present a dynamical system analysis of the tachyon dark energy model by parametrization of the equation of state (EoS) of the dark energy. The choice of parametrization can constrain the form of the field potential, and as a result, the theory can be directly constrained from the observation without assuming a particular form of the potential.
