چکیده
The cosmological evolution in Nonlinear Born-Infeld(hereafter NLBI) scalar field theory with negative potentials was investigated. The cosmological solutions in some important evolutive epoches were obtained. The different evolutional behaviors between NLBI and linear scalar field theory have been presented. A notable characteristic is that NLBI scalar field behaves as ordinary matter nearly the singularity while the linear scalar field behaves as " stiff " matter. We find that in order to accommodate current observational universe the value of potential parameters |m| and |V 0 | must have an upper bound. We compare different cosmological evolutions for different potential parameters m, V 0

The inflationary attractor properties of the canonical scalar field and Born-Infeld field are investigated in the Randall-Sundrum II scenario with a Gauss-Bonnet term in the bulk action. We find that the inflationary attractor property will always hold for both the canonical and Born-Infeld fields for any allowed non-negative Gauss-Bonnet coupling. We also briefly discuss the possibility of exp...

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,...
