Let ${\mathcal A}(t)=\langle\psi_0,\psi_t\rangle$ be the survival amplitude and ${\mathcal P}(t)=|{\mathcal A}(t)|^2$ the survival probability. In the regime where quantum-resonanc…

Consider waves on the exterior of a stationary black hole, and assume that uniform boundedness holds. No favorable geometric structure for trapping is assumed. Universal decay conj…
