| ABSTRACT: |
Coset methods are used to construct the effective action describing the dynamics of the (massive) Nambu Goldstone scalar degree of freedom associated with the spontaneous breaking of the isometry group of AdSd+1 space to that of an AdSd subspace. The resulting action is an SO(2,d) invariant AdS form of the Nambu Goto action. When the isometry group is gauged, the Goldstone degree of freedom is shown to be eaten by a vector boson which now describes the fluctuations of the AdSd brane in its co-volume. The resulting theory is AdSd gravity coupled to a massive, brane localized vector boson.
