Description

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 $ω_ϕ\sim-1$, $Ω_ϕ=1$, which avoid the "Big rip" problem and meets the current observations well.
