Some of the electromagnetic modes do not oscillate, they only decay, since they have pure imaginary frequencies. The gravitational modes show peculiar features: the odd and even gravitational perturbations no longer have the same characteristic quasinormal frequencies. There is a special mode for odd perturbations whose behavior differs completely from the usual one in scalar<jats:sup>1<\/jats:sup> and electromagnetic perturbation in an AdS spacetime, but has a similar behavior to the Schwarzschild black hole<jats:sup>3<\/jats:sup> in an asymptotically flat spacetime: the imaginary part of the frequency goes as [Formula: see text], where r<jats:sub>+<\/jats:sub> is the horizon radius. We also investigated the small black hole limit showing that the imaginary part of the frequency goes as [Formula: see text]. These results are important to the AdS\/CFT<jats:sup>4<\/jats:sup> conjecture since according to it the QNMs describe the approach to equilibrium in the conformal field theory.
