Cosmological Evolution of Dirac-Born-Infeld Field
We investigate the cosmological evolution of the system of a
Dirac-Born-Infeld field plus a perfect fluid. We analyze the existence and
stability of scaling solutions for the AdS throat and the quadratic potential.
We find that the scaling solutions exist when the equation of state of the
perfect fluid is negative and in the ultra-relativistic limit.Comment: 9 pages, 1 figure, LaTeX2e, references added, accepted for
