Propagators from characteristic surfaces
Jorge Conde
We study the Goursat or characteristic problem, i.e. a hyperbolic equation with given data on a surface (the half of the standard Cauchy problem), with some kind of dimensional reg…
Goursat's Problem and the Holographic Principle
Enrique Alvarez, Jorge Conde, Lorenzo Hernandez
The whole idea of holography as put forward by Gerard 't Hooft assumes that data on a boundary determine physics in the volume. This corresponds to a Dirichlet problem for euclidea…
The Dirichlet Obstruction in AdS/CFT
Enrique Alvarez, Jorge Conde, Lorenzo Hernandez
The obstruction for a perturbative reconstruction of the five-dimensional bulk metric starting from the four-dimensional metric at the boundary,that is, the Dirichlet problem, is c…
Codimension Two Holography
Enrique Alvarez, Jorge Conde, Lorenzo Hernandez
A holographic interpretation for some specific Ricci flat string backgrounds of the form is proposed. The conjecture is that there is a Four-dimensional Euclidean C…
A Note on the Bach Tensor in AdS/CFT
Enrique Alvarez, Jorge Conde, Lorenzo Hernandez
This paper has been superseded by hep-th/0303164, "The Dirichlet Obstruction in AdS/CFT"
Rudiments of Holography
Enrique Alvarez, Jorge Conde, Lorenzo Hernandez
An elementary introduction to Maldacena's AdS/CFT correspondence is given, with some emphasis in the Fefferman-Graham construction. This is based on lectures given by one of us (E.…
