Abstract
We study brane-world solutions of five-dimensional supergravity in singular spaces. We exhibit a self-tuned four-dimensional cosmological constant whe n five-dimensional supergravity is broken by an arbitrary tension on the br ane-world. The brane-world metric is of the FRW type corresponding to a cos mological constant Omega (Lambda) = 5/7 and an equation of state omega = -5 /7 which are consistent with experiment.
