An approach to quasinormal modes of black hole based on reversed harmonic oscillator dynamics

Shigefumi Naka, Haruki Toyoda

The frequencies of quasinormal modes (QNM) for the Schwartzschild black hole are studied from the viewpoint of the particle scattering under an effective Regge-Wheeler type of pote…
