چکیده

In this paper, we are going to study quintom dark energy cosmological model. In that case we introduce the action of gravity which is minimally couple to scalar field φ and σ with potential V (φ,σ). First we write the Lagrangian of corresponding model in FRW model. Here we also introduce the non-commutative geometry and modify the above model. The deformed model leads us to obtain the equation of state. And finally we discus the present cosmological in case of phantom and quintessence. And also, we investigate the critical point and stability of system.
