Abstract

We investigate the cosmology of (4 + 1)-dimensional gravity coupled to a scalar field and a bulk anisotropic fluid within the context of the single-brahe Randall-Sundrum scenario. Assuming a separable metric, a static fifth radius and the scalar to depend only on the fifth direction, we find that the warp factor is given as in the papers of Kachru, Schulz and Silverstein "Phys. Rev. D 62 (2000) 045021, Phys. Rev. D (2000) 085003" and that the cosmology on a self-tuning brane is standard. In particular, for a radiation-dominated brane the pressure in the fifth direction vanishes.
