Three-dimensional asymptotically flat Einstein-Maxwell theory
Glenn Barnich, Pierre-Henry Lambert, Pujian Mao
Three-dimensional Einstein-Maxwell theory with non trivial asymptotics at null infinity is solved. The symmetry algebra is a Virasoro-Kac-Moody type algebra that extends the bms3 a…
Liouville theory beyond the cosmological horizon
Geoffrey Compère, Laura Donnay, Pierre-Henry Lambert +1
The dS/CFT correspondence postulates the existence of a Euclidean CFT dual to a suitable gravity theory with Dirichlet boundary conditions asymptotic to de Sitter spacetime. A semi…
Conformal symmetries of gravity from asymptotic methods: further developments
Pierre-Henry Lambert
In this thesis, the symmetry structure of gravitational theories at null infinity is studied further, in the case of pure gravity in four dimensions and also in the case of Einstei…
Einstein-Yang-Mills theory : I. Asymptotic symmetries
Glenn Barnich, Pierre-Henry Lambert
Asymptotic symmetries of the Einstein-Yang-Mills system with or without cosmological constant are explicitly worked out in a unified manner. In agreement with a recent conjecture,…
Introduction to Black Hole Evaporation
Pierre-Henry Lambert
These lecture notes are an elementary and pedagogical introduction to the black hole evaporation, based on a lecture given by the author at the Ninth Modave Summer School in Mathem…
Asymptotic symmetries at null infinity and local conformal properties of spin coefficients
Glenn Barnich, Pierre-Henry Lambert
We show that the symmetry algebra of asymptotically flat four dimensional spacetimes at null infinity in the sense of Newman and Unti is isomorphic to the direct sum of the abelian…
