Quantitative Mode Stability for the Wave Equation on the Kerr Spacetime [PDF]
Yakov Shlapentokh-RothmanWe give a quantitative refinement and simple proofs of mode stability type statements for the wave equation on Kerr backgrounds in the full sub-extremal range (|a| < M). As an application, we are able to quantitatively control the energy flux along the horizon and null infinity and establish integrated local energy decay for solutions to the wave equation in any bounded-frequency regime.View original: http://arxiv.org/abs/1302.6902
