چکیده
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, Ωϕ = 1, which avoid the " Big rip " problem and meets the current observations well.

In this paper, we regard dilaton in Weyl-scaled induced gravitational theory as a coupled quintessence. Based on this consideration, we investigate the dilaton coupled quintessence(DCQ) model in 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...

We considered the phantom cosmology with a lagrangian L = 1 η [1− 1 + ηg µν φ , µ φ , ν ]− u(φ), which is original from the nonlinear Born-Infeld type scalar field with the lagrangian L = 1 η [1 − 1 − ηg µν φ , µ φ , ν ] − u(φ). This cosmological model can explain the accelerated expansion of the universe with the equation of state parameter w ≤ −1. We get a sufficient condition for a arbitrary...

A quantum model of gravitation interacting with a Born-Infeld(B-I) type scalar field ϕ is considered. The corresponding Wheeler-Dewitt equation can be solved analytically for both very large and small ˙ ϕ. In the extreme limits of small cosmological scale factor the wave function of the universe can be obtained by applying the methods developed by Vilenkin, Hartle and Hawking. We also suggest t...
