Quantum gravity in the region very near the horizon of an extreme Kerr black hole (whose
angular momentum and mass are related by J= GM 2) is considered. It is shown that …

We show that the linearization of all exact solutions of classical chiral gravity around the AdS
3 vacuum have positive energy. Nonchiral and negative-energy solutions of the linearized …

The treatment of exact conservation laws in Lagrangian gauge theories constitutes the main
axis of the first part of the thesis. The formalism is developed as a self-consistent theory but …

We apply the recent derivations of dual charges in asymptotically flat spacetimes to
asymptotically locally anti–de Sitter (AdS) spacetimes. In contrast to the results in the flat …

A bstract The asymptotic structure of three-dimensional higher-spin anti-de Sitter gravity is
analyzed in the metric approach, in which the fields are described by completely symmetric …

Scalar fields coupled to three-dimensional gravity are considered. We uncover a scaling
symmetry present in the black hole reduced action, and use it to prove a Smarr formula valid …

A bstract We study asymptotic charges for symmetric massless higher-spin fields on Anti de
Sitter backgrounds of arbitrary dimension within the canonical formalism. We first analyse in …

A bstract We define a class of space-times that we call asymptotically locally Schrödinger
space-times. We consider these space-times in 3 dimensions, in which case they are also …

The calculation of conserved charges of black holes is a rich problem, for which many
methods are known. Until recently, there was some controversy on the proper definition of …

We obtain the Killing equations and the corresponding infinitesimal isometries for ten-
dimensional space generated by a large number of coincident D3-branes. In a convenient …
