Abstract

Abstract The WKB approach for finding quasinormal modes of black holes, suggested in Schutz and Will (1985 Astrophys. J. Lett . 291 L33–6) by Schutz and Will at the first order and later developed to higher orders (Iyer and Will 1987 Phys. Rev . D 35 3621; Konoplya 2003 Phys. Rev . D 68 024018; Maty...
