Canonical quantization and black hole perturbations
Zoltan Perjes, Arpad Lukacs
We examine the possibility of a constraint-free quantization of linearized gravity, based on the Teukolsky equation for black hole perturbations. We exhibit a simple quadratic (but…
Petrov classification of perturbed spacetimes: the Kasner example
Christian Cherubini, Donato Bini, Marco Bruni +1
In this paper we consider vacuum Kasner spacetimes, focusing on those that can be parametrized as linear perturbations of the special Petrov type D case. For these quasi-D Kasner m…
Principal null directions of perturbed black holes
Z. Perjés, M. Vasúth
The properties of principal null directions of a perturbed black hole are investigated. It shown that principal null directions are directly observable quantities characterizing th…
Perturbations of rotating cosmological black holes
Zoltán Perjés
Charged, rotating black hole solutions of Einstein's gravitational equations are investigated in the presence of a cosmological constant. A pair of wave equations governing the ele…
Charged black holes: Wave equations for gravitational and electromagnetic perturbations
Zoltán Perjés, Mátyás Vasúth
A pair of wave equations for the electromagnetic and gravitational perturbations of the charged Kerr black hole are derived. The perturbed Einstein-Maxwell equations in a new gauge…
