Abstract
We show that the singular sources in the energy-momentum tensor for the Ran dall-Sundrum brane, world, viewed as a solution of type IIB supergravity, a re composed of two elements. One of these is a D3-brane source with tension opposite in sign to the RS tension in five dimensions: the other arises fr om patching two regions of flat ten-dimensional spacetime. This resolves an apparent discrepancy between supersymmetry and the sign and magnitude of t he RS tension. (C) 2001 Published by Elsevier Science B.V.
