Although this spacetime configuration is nowadays hard to suppose, it can be very important in the early universe, when the wormhole spacetime foam representation can be meaningful. We compare our approach with the no-boundary prescription of Hartle-Hawking.Revtex 3.0, preprint,amsfonts 19 pagesGeneral Relativity and Quantum CosmologyHigh Energy Physics - Theorytext
