On the past 13th of October, Dr. Rodrigo Olea gave a seminar at the University of Torino, for the String Theory Group. The talk was titled “Conformal Renormalization and Energy Functionals in AdS gravity” here we leave the abstract.
Abstract:
Within a holographic framework, we explore the physical consequences of embedding Einstein-AdS gravity in Conformal Gravity in four and six dimensions. In the bulk, the procedure is equivalent to Holographic Renormalization, as the Einstein-AdS action appears augmented by the correct boundary counterterms. In codimension-2 surfaces, 4D Conformal Gravity induces a conformal invariant which, for given conditions on the ambient space and the surface itself, reproduces different functionals: Renormalized Area, Willmore Energy and Reduced Hawking Mass.
