On the quasinormal modes of the de Sitter spacetime

arXiv:1207.6791 · doi:10.1007/s10714-012-1398-4

Abstract

Modifying a method by Horowitz and Hubeny for asymptotically anti-de Sitter black holes, we establish the classical stability of the quasinormal modes of the de Sitter spacetime. Furthermore using a straightforward method we calculate the de Sitter quasinormal frequencies of the gravitational perturbations and discuss some properties of the radial functions of these quasinormal modes.
