at: 13:15 room S5.20 abstract: | As an alternative to the Holographic Renormalization procedure in the context of AdS/CFT correspondence, we introduce a regularization scheme for AdS gravity based on the addition of boundary terms which are a given polynomial of the extrinsic and intrinsic curvatures (Kounterterms). These terms are closely related to either topological invariants or Chern-Simons densities in the corresponding dimension, they can be easily generalized to other gravity theories (Einstein-Gauss-Bonnet, Lovelock, etc.). We provide a general prescription on how to obtain standard holographic quantities at the boundary. We also briefly comment on a possible relation to supersymmetry. |
