Minkowski and (A)dS ground states in general 2d dilaton gravity
Daniel Grumiller, Martin Laihartinger, Romain Ruzziconi
We reorganize the derivative expansion of general (power-counting non-renormalizable) 2d dilaton gravity such that the mass function is integrable. As an example, we consider a thr…
Coadjoint representation of the BMS group on celestial Riemann surfaces
Glenn Barnich, Romain Ruzziconi
The coadjoint representation of the BMS group in four dimensions is constructed in a formulation that covers both the sphere and the punctured plane. The structure constants are wo…
Conservation and Integrability in Lower-Dimensional Gravity
Romain Ruzziconi, Céline Zwikel
We address the questions of conservation and integrability of the charges in two and three-dimensional gravity theories at infinity. The analysis is performed in a framework that a…
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…
On the Various Extensions of the BMS Group
Romain Ruzziconi
The Bondi-Metzner-Sachs-van der Burg (BMS) group is the asymptotic symmetry group of radiating asymptotically flat spacetimes. It has recently received renewed interest in the cont…
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…
