A new type of nonsingular black-hole solution in general relativity
F. R. Klinkhamer
Certain exact solutions of the Einstein field equations over nonsimply-connected manifolds are reviewed. These solutions are spherically symmetric and have no curvature singularity…
Black-hole solution without curvature singularity and closed timelike curves
F. R. Klinkhamer
With a prescribed Coulomb-type energy-momentum tensor, an exact solution of the Einstein field equations over a nonsimply-connected manifold is presented. This spherically symmetri…
Black-hole solution without curvature singularity
F. R. Klinkhamer
An exact solution of the vacuum Einstein field equations over a nonsimply-connected manifold is presented. This solution is spherically symmetric and has no curvature singularity.…
A nonsingular spacetime defect
F. R. Klinkhamer, C. Rahmede
A nonsingular localized static classical solution is constructed for standard Einstein gravity coupled to an chiral model of scalars (Skyrme model). This soluti…
Standard Model Higgs field and energy scale of gravity
F. R. Klinkhamer
The effective potential of the Higgs scalar field in the Standard Model may have a second degenerate minimum at an ultrahigh vacuum expectation value. This second minimum then dete…
