A New Boundary Counterterm for Asymptotically AdS Spacetimes
@article{McNees2005ANB, title={A New Boundary Counterterm for Asymptotically AdS Spacetimes}, author={Robert A. McNees}, journal={arXiv: High Energy Physics - Theory}, year={2005} }
We present a modified version of the boundary counterterm method for removing divergences from the action of an asymptotically $AdS$ spacetime. The standard approach renders the action finite but leaves diffeomorphism invariance partially broken if the dimension of the spacetime is odd. We show that this symmetry is restored by a new boundary counterterm, needed to cancel a divergence that appears in dimensional regularization. The result is a finite, diffeomorphism invariant action appropriate…
