Some exact quasi-normal frequencies of a massless scalar field in the Schwarzschild space-time
arXiv:1807.04513 · doi:10.1103/PhysRevD.98.024017
Abstract
We show that not all quasinormal modes of a massless scalar field in the Schwarzschild metric are encoded in the corresponding characteristic equation expressed by means of a continued fraction. We provide an analytical formula for these new hitherto missing quasinormal modes, and in doing that we also construct a generalization of the Gauss convergence criterion.
