Asymptotic symmetry algebra of Einstein gravity and Lorentz generators
Oscar Fuentealba, Marc Henneaux, Cédric Troessaert
The asymptotic symmetry algebra of four-dimensional Einstein gravity in the asymptotically flat context has been shown recently to be the direct sum of the Poincaré algebra and of…
A note on the asymptotic symmetries of electromagnetism
Oscar Fuentealba, Marc Henneaux, Cédric Troessaert
We extend the asymptotic symmetries of electromagnetism in order to consistently include angle-dependent gauge transformations that involve terms growing at spatial infi…
Logarithmic supertranslations and supertranslation-invariant Lorentz charges
Oscar Fuentealba, Marc Henneaux, Cédric Troessaert
We extend the BMS(4) group by adding logarithmic supertranslations. This is done by relaxing the boundary conditions on the metric and its conjugate momentum at spatial infinity in…
Asymptotic structure of the gravitational field in five spacetime dimensions: Hamiltonian analysis

Oscar Fuentealba, Marc Henneaux, Javier Matulich +1
We study asymptotically flat spacetimes in five spacetime dimensions by Hamiltonian methods, focusing on spatial infinity and keeping all asymptotically relevant nonlinearities in…

The asymptotic structure of the Pauli-Fierz theory at spatial infinity is investigated in four spacetime dimensions. Boundary conditions on the massless spin- field that are inv…

We develop basic tools and matching conditions to interpolate between asymptotic and near horizon symmetries. We focus on black holes in three dimensions. In particular, we match B…
The asymptotic structure of gravity at spatial infinity in four spacetime dimensions
Marc Henneaux, Cédric Troessaert
A review of our results on the asymptotic structure of gravity at spatial infinity in four spacetime dimensions is given. Finiteness of the action and integrability of the asymptot…

Marc Henneaux, Cedric Troessaert
We investigate the asymptotic structure of electromagnetism in Minkowski space in even and odd spacetime dimensions . We focus on since the case has been studie…
Asymptotic structure of a massless scalar field and its dual two-form field at spatial infinity
Marc Henneaux, Cedric Troessaert
Relativistic field theories with a power law decay in at spatial infinity generically possess an infinite number of conserved quantities because of Lorentz invariance. Mos…

Marc Henneaux, Cédric Troessaert
We present a new set of asymptotic conditions for gravity at spatial infinity that includes gravitational magnetic-type solutions, allows for a non-trivial Hamiltonian action of th…

Marc Henneaux, Cédric Troessaert
We analyse the asymptotic symmetries of Maxwell theory at spatial infinity through the Hamiltonian formalism. Precise, consistent boundary conditions are explicitly given and shown…
BMS Group at Spatial Infinity: the Hamiltonian (ADM) approach
Marc Henneaux, Cédric Troessaert
New boundary conditions for asymptotically flat spacetimes are given at spatial infinity. These boundary conditions are invariant under the BMS group, which acts non trivially. The…

We show how a global BMS4 algebra appears as the asymptotic symmetry algebra at spatial infinity. Using linearised theory, we then show that this global BMS4 algebra is the one int…

Glenn Barnich, Cédric Troessaert, David Tempo +1
The theory of massive gravity proposed by Bergshoeff, Hohm and Townsend is considered in the special case of the pure irreducibly fourth order quadratic Lagrangian. It is shown tha…

In this work, we interpret part of the boundary conditions as external sources in order to solve the integrability problem present in the computation of surface charges associated…

This thesis is divided in two parts. The first part contains the study of some properties of the electromagnetic duality in 4 dimensions. An extended double potential formalism for…
Canonical Structure of Field Theories with Boundaries and Applications to Gauge Theories
Cedric Troessaert
In this paper, we present a review of the canonical structure of field theories defined on manifolds with time-like boundaries. The notion of differentiable generator is shown to b…
Comments on holographic current algebras and asymptotically flat four dimensional spacetimes at null infinity

Enhanced asymptotic symmetry algebra of AdS3
Cedric Troessaert
A generalization of the Brown-Henneaux boundary conditions is introduced for pure gravity with negative cosmological constant in 3 dimensions. This leads to new degrees of freedom…
