A note on the area of event horizon of Kleinian black hole
arXiv:2405.16689 · doi:10.1140/epjc/s10052-024-13346-9
Abstract
We point out that the area of event horizon of Kleinian black hole is infinite due to the fact that its event horizon is not a sphere but a hyperboloid. Therefore, the usual interpretations of Schwarzschild black hole might not be applicable to the Kleinian black hole.
