A new type of nonsingular black-hole solution in general relativity
F.R. Klinkhamer ;
Date 26 Sep 2013
AbstractCertain exact solutions of the Einstein field equations over nonsimply-connected manifolds are reviewed. These solutions are spherically symmetric and have no curvature singularity. They can be considered to regularize the Schwarzschild solution with a curvature singularity at the center. Spherically symmetric collapse of matter in R^4 may result in these nonsingular black-hole solutions, if quantum-gravity effects allow for topology change near the center or if the nontrivial topology is already present as a remnant from a quantum spacetime foam.
