Quasinormal modes of Reissner-Nordström-AdS black holes under physical field-vanishing boundary conditions
Hui-Fa Liu, Qi Su, Ding-fang Zeng
Boundary conditions play a key role in determining the perturbation behavior of a black hole. Motivated by two guiding principles for single-field perturbations -- the non-deformat…

Master functions of Reissner-Nordstrom black hole perturbations and their Darboux transformation
Hui-Fa Liu, Ding-fang Zeng
Lenzi and Sopuerta developed a new method to construct master functions for the perturbation of vacuum black holes. We extend this method to black holes coupled with electromagneti…
