plane (ω is the equation of state parameter of the dark energy) [4–12, 14–19, 21–25]). In the present study we desire to perform our investigation in the case of quintom cosmology, constructed using both quintessence (σ) and phantom (φ) fields, mantaining a nonspecific potential form V(φ, σ). There are many works in the literature that deals with this type of problems, but in a general way, and not with a particular ansatz, one that considers dynamical systems [12, 13, 20]. One special class of potentials used to study this behaviour corresponds to the case of the exponential potentials [4, 6, 9, 26, 28] for each field, where the corresponding energy density of a scalar field has the range of scaling behaviors [29, 30], i.e, it scales exactly as a power of the scale factor like, ρφ ∝ a , when the dominant component has an energy density which scales in a similar way. There are other works where other type of potentials are analyzed [1, 9, 15, 19, 20, 23, 24, 31].
