A coherent approach to Spacetime Foam
A coherent superposition of N Schwarzschild wormholes is proposed as a model
for spacetime foam. Following the subtraction procedure for manifolds with
boundaries, we calculate by variational methods the Casimir energy. A proposal
for an alternative foamy model formed by N Schwarzschild-Anti-de Sitter
wormholes is here considered. Finally, a conjecture about the foam evolution is
proposed.Comment: 3 pages. To be submitted to the proceedings of the 3rd Workshop of
