dc.description.abstract
We investigate the link between the warp function and the potential in Dirac-Born-Infeld (DBI) power-law cosmologies. We give a prescription to take advantage of the fact that there is always a choice of potential resulting in a constant ratio between pressure and energy density for a given a warp factor. We illustrate the method with several examples, and complete the investigation by showing how symmetries can be used to generate new DBI solutions from existing ones.
