A derivative-free optimization method to compute scalar perturbation of AdS black holes
Rodrigo S. Lima, Alan B. Pavan
In this work we describe an interesting application of a simple derivative-free optimization method to extract the quasinormal modes (QNM's) of a massive scalar field propagating i…
