Abstract

Price's Law states that linear perturbations of a Schwarzschild black hole fall off as t-2ℓ-3 for t→∞ provided the initial data decay sufficiently fast at spatial infinity. Moreover, if the perturbations are initially static (i.e., their time derivative is zero), then the decay is predicted to be t-2ℓ-4. We give a proof of t-2ℓ-2 decay for general data in the form of weighted L1 to L∞ bounds for solutions of the Regge-Wheeler equation. For initially static perturbations we obtain t-2ℓ-3. The proof is based on an integral representation of the solution which follows from self-adjoint spectral theory. We apply two different perturbative arguments in order to construct the corresponding spectral measure and the decay bounds are obtained by appropriate oscillatory integral estimates.
