Black-Hole Perturbations  

In General blue bullet s.a. black-hole phenomenology; quasinormal modes; chaotic motion; horizons; numerical black holes; quantum black holes.
* Stability: Stationary (M > 0) black holes are stable under local perturbations; The proof uses the fact that the linearized field equations imply the vanishing of an integral which would not vanish for frequencies with positive imaginary part; M < 0 black holes are unstable.

* Description: Massless fields of spin s = 1/2, 1, 3/2, or 2 are usually described in terms of Weyl scalars ψ4 and ψ0, which satisfy Teukolsky's complex master equation, a wave equation with added curvature terms, and respectively represent outgoing and ingoing radiation; They can also be described in terms of (Hertz-like) potentials Ψ in outgoing or ingoing radiation gauges; Equations describing massive spin-1 fields have not been shown to be separable.
