Quasinormal modes of Reissner-Nordstrom Anti-de Sitter black holes

Complex frequencies associated with quasinormal modes for large Reissner-No rdstrom Anti-de Sitter black holes have been computed. These frequencies ha ve close relation to the black hole charge and do not linearly scale with t he black hole temperature as in Schwarzschild Anti-de Sitter case. In terms of AdS/CFT correspondence, we found that the bigger the black hole charge is, the quicker for the approach to thermal equilibrium in the CFT. The pro perties of quasinormal modes for l > 0 have also been studied. (C) 2000 Els evier Science B.V. All rights reserved.
