Lie Algebroids and the Geometry of Off-shell BRST
Luca Ciambelli, Robert G. Leigh
It is well-known that principal bundles and associated bundles underlie the geometric structure of classical gauge field theories. In this paper, we explore the reformulation of ga…
Topological Terms and the Misner String Entropy
Luca Ciambelli, Cristóbal Corral, José Figueroa +2
The method of topological renormalization in anti-de Sitter (AdS) gravity consists in adding to the action a topological term which renders it finite, defining at the same time a w…
Weyl Charges in Asymptotically Locally AdS Spacetimes
Francesco Alessio, Glenn Barnich, Luca Ciambelli +2
We discuss an enhancement of the Brown-Henneaux boundary conditions in three-dimensional AdS General Relativity to encompass Weyl transformations of the boundary metric. The result…
New Chiral Gravity
Luca Ciambelli, Stéphane Detournay, Antoine Somerhausen
The phase space of three-dimensional gravity with Compere-Song-Strominger (CSS) boundary conditions is endowed with asymptotic symmetries consisting in the semi-direct product of a…
Fefferman-Graham and Bondi Gauges in the Fluid/Gravity Correspondence
Luca Ciambelli, Charles Marteau, P. Marios Petropoulos +1
In three-dimensional gravity, we discuss the relation between the Fefferman--Graham gauge, the Bondi gauge and the Eddington--Finkelstein type of gauge, often referred to as the de…
Gauges in Three-Dimensional Gravity and Holographic Fluids
Luca Ciambelli, Charles Marteau, P. Marios Petropoulos +1
Solutions to Einstein's vacuum equations in three dimensions are locally maximally symmetric. They are distinguished by their global properties and their investigation often requir…
