La. Anchordoqui et Sep. Bergliaffa, Wormhole surgery and cosmology on the brane: The world is not enough - art. no. 067502, PHYS REV D, 6206(6), 2000, pp. 7502
We show that the five-dimensional model introduced by Randall and Sundrum i
s (one-half of) a wormhole, and that this is a general result in models of
the RS type. We also present a simple model of brane-world cosmology in whi
ch the background is a static anti-de Sitter manifold, and the location of
the two 3-branes is determined by the technique of "surgical grafting."
