Die Durchdringungslinien von Vielflachens. Both Schwarzschild and Kerr spacetimes are stationary and possess certain symmetries. A study of geodesies (corresponding to the motion of test particles and light rays) and wave fields in these metrics enabled us to describe a number of interesting and important features of physical effects in t

Die Durchdringungslinien von Vielflachenlyzing the efficiency of energy extraction from black holes. Recall that although a black hole is by definition a region of no escape for material bodies and light rays, situations are possible in which energy can be extracted via certain physical processes. We will see later that this energy is ext

Lehrbuch der darstellenden Geometrieo observation by distant observers. At first glance, black hole electrodynamics is quite trivial. Indeed, the electromagnetic field of a stationary black hole (of a given mass .) is determined unambiguously by its electric charge . and rotation parameter .. If the charged black hole does not rotate,

Lehrbuch der darstellenden Geometrieare, indeed, insignificant for black holes of about a solar mass (and greater). However, for a small-mass (primordial) black hole these effects cannot be ignored; in fact, they qualitatively change the black hole’s evolution. They are also likely to become important for those regions inside a black

Die Ellipse: Konjugierte Durchmessersehnen drawing the inevitable conclusion that the particle flux to infinity which carries away positive energy is accompanied by a flux of negative energy across the horizon into the black hole. This would be impossible in classical theory, with ordinary physical assumptions satisfied (energy dominance co
