Born-Infeld Type Phantom Model in the ω-ω' Plane
Abstract
In this paper, we investigate the dynamics of Born-Infeld(B-I) phantom model in the ω-ω' plane, which is defined by the equation of state parameter for the dark energy and its derivative with respect to N(the logarithm of the scale factor a). We find the scalar field equation of motion in ω-ω' plane, and show mathematically the property of attractor solutions which correspond to ωφ-1, φ=1, which avoid the "Big rip" problem and meets the current observations well.
