Abstract
In this chapter we consider perturbations and stability of higher dimensional black holes focusing on the static background case. We first review a gaugeinvariant formalism for linear perturbations in a fairly generic class of (m+n)dimensional spacetimes with a warped prodnct metric, including black hole geometry. We classify perturbations of such a background into three types, the tensor, vector and scalartype, according to their tensorial behavior on the ndimensional part of the background spacetime, and for each type of perturbations, we introduce a set of manifestly gauge invariant variables. We then introduce harmonic tensors and write down the equations of motion for the expansion coefficients of the gauge invariant perturbation variables in terms of the harmonics. In particular, for the tensortype perturbations a single master equation is obtained in the (m+n)dimensional background, which is applicable for perturbation analysis of not only static black holes but also some class of rotating black holes as well as blackbranes. For the vector and scalar type, we derive a set of decoupled master equations when the background is a (2+n)dimensional static black hole in the EinsteinMaxwell theory with a cosmological constant. As an application of the master equations. we review the stability analysis of higher dimensional charged static black holes with a cosmological constant. We also briefly review the recent results of a generalization of the perturbation formulae presented here and stability analysis to static black holes in generic Lovelock theory.
