| contents | Conserved Gravitational Charges, Locality and the Holographic Weyl Anomaly - a Fresh Viewpoint Pedro Lauridsen Ribeiro Física, Astronomía y Matemáticas Since the proposal of the AdS/CFT correspondence, made by Maldacena and Witten, there has been somecontroversy about the definition of conserved Noether charges associated with asymptotic isometries in asymptoticallyAdS spacetimes, namely, whether they form an anomalous (i.e., a nontrivial central extension)representation of the Lie algebra of the conformal group in odd bulk dimensions or not. In the present work, weshall review the derivation of these charges by using covariant phase space techniques, emphasizing the principleof locality underlying it. We shall also comment on how these issues manifest themselves in the quantumsetting. 2005 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46435733 en http://www.redalyc.org/revista.oa?id=464 Brazilian Journal of Physics application/pdf Sociedade Brasileira de Física Brazilian Journal of Physics (Brasil) Num.4B Vol.35 |
