Holographic renormalization and the variational problem for mixed boundary conditions via a solution-dependent superpotential-like function
David Choque, Raúl Rojas
We study holographic renormalization and the variational problem in four-dimensional Einstein gravity coupled to a self-interacting scalar field in asymptotically AdS spacetimes wi…

Dumitru Astefanesei, Gonzalo Casanova, Raul Rojas
We propose a new way to relate the black hole thermodynamics and geometry by generalizing the Euclidean formalism to include "virtual geometries", which do not necessarily satisfy…
