Phys. Rev. D 62, 084015 (2000) [14 pages]Gauge-invariant gravitational perturbations of maximally symmetric spacetimesReceived 11 April 2000; published 22 September 2000 Gravitational perturbations of anti–de Sitter (AdS) spacetime play important roles in the AdS conformal field theory correspondence and the brane world scenario. In this paper, we develop a gauge-invariant formalism of gravitational perturbations of maximally symmetric spacetimes including anti–de Sitter spacetime. The existence of scalar-type master variables is shown and the corresponding master equations are derived. © 2000 The American Physical Society URL:
