Thermodynamics, topology and dimension of initial real tunneling manifolds
arXiv:gr-qc/9712059
Abstract
We develop the argument that initial real tunneling in quantum gravity be contemplated as a thermodynamical analogous to a black hole condensate in equilibrium with Hawking's radiation in a box. The total entropy is always maximized in the Lorentzian sector of the manifold, and, in this sense, tunneling is predicted.
