Bounds for axially symmetric linear perturbations for the extreme Kerr black hole
(2015)We obtain remarkably simple integral bounds for axially symmetric linear perturbations for the extreme Kerr black hole in terms of conserved energies. From these estimates we deduce pointwise bounds for the perturbations ... -
Nonmodal linear stability of the Schwarzschild black hole
(2014)A proof is given that the space L of solutions of the linearized vacuum Einstein equation around a Schwarzschild black hole is parametrized by two scalar fields, which are gauge invariant combinations of perturbed algebraic ...
