    Dec 15, 2009 · H.T. Cho (Tamkang U.), A.S. Cornell (Witwatersrand U.), Jason Doukas (Kyoto U., Yukawa Inst., Kyoto), Wade Naylor (Doshisha U. & Osaka U.) In this article we show that the asymptotic iteration method (AIM) allows one to numerically find the quasinormal modes of Schwarzschild and Schwarzschild de Sitter (SdS) black holes.

    We discuss an approach to obtaining black hole quasinormal modes (QNMs) using the asymptotic iteration method (AIM), initially developed to solve second order ordinary di erential equations. We introduce the standard version of this method and present an improvement more suitable for numerical implementation.
