Spacetimes foliated by nonexpanding and Killing horizons: Higher dimension
Spacetimes foliated by nonexpanding and Killing horizons: Higher dimension
The theory of nonexpanding horizons (NEHs) geometry and the theory of near-horizon geometries (NHGs) are two mathematical relativity frameworks generalizing the black hole theory. From the point of view of the NEHs theory, a NHG is just a very special case of a spacetime containing a NEH of many extra …
