Existence of quasinormal modes for Kerr-AdS black holes
arXiv:1602.08147 · doi:10.1007/s00023-017-0568-z
Abstract
This paper establishes the existence of quasinormal frequencies converging exponentially to the real axis for the Klein--Gordon equation on a Kerr-AdS spacetime when Dirichlet boundary conditions are imposed at the conformal boundary. The proof is adapted from results in Euclidean scattering about the existence of scattering poles generated by time-periodic approximate solutions to the wave equation.
