Titre Relaxing the Bondi gauge in 3d and 4d gravity
Résumé The Bondi gauge is a convenient choice of coordinates and line element to analyze the asymptotic structure of general relativity and aspects of gravitational radiation. Over the recent years several relaxations of the boundary conditions have been proposed, with the aim of understanding how general the asymptotic structure should be considered, and how large the asymptotic symmetry algebra can become. After presenting some motivations related to the understanding of charges, integrability, and flux in the covariant phase space formalism, I will review some recently proposed relaxations of the Bondi gauge in 3d and 4d gravity.
