Neutrino quasinormal modes of a Kerr–Newman– de Sitter black hole

Using the Poshl-Teller approximation, we evaluate the neutrino quasinormal modes (QNMs) of a Kerr-Newman-de Sitter black hole. The result shows that for a Kerr-Newman-de Sitter black hole, massless neutrino perturbation of large A, positive m and small value of n will decay slowly. (c) 2005 Elsevier B.V. All rights reserved.
