Note on the bondi-metzner-sachs group
WebAs in the Bondi-Metzner-Sachs gauge, it is shown to be isomorphic to the direct sum of the abelian algebra of infinitesimal conformal rescalings with . The latter algebra is the semidirect sum of infinitesimal supertranslations with the conformal Killing vectors of the Riemann sphere. In gravitational theory, the Bondi–Metzner–Sachs (BMS) group, or the Bondi–van der Burg–Metzner–Sachs group, is an asymptotic symmetry group of asymptotically flat, Lorentzian spacetimes at null (i.e., light-like) infinity. It was originally formulated in 1962 by Hermann Bondi, M. G. van der Burg, A. W. Metzner and Rainer K. Sachs in order to investigate the flow of energy at infinity due to propagating gravitational waves. Half a century later, this work of Bondi, van der B…

Thus there WebIn [PS22], we studied the Lie group structure of the Bondi–Metzner–Sachs (BMS) group [BBM62,Sac62] from the viewpoint of infinite-dimensional geometry. The BMS group is defined as the subgroup of spacetime-diffeomorphisms that preserve asymp-totic flatness in the sense of Bondi, Van der Burg, Metzner and Sachs. Asymptotically

WebYou can look back at the original paper in which Sachs first constructed the full BMS group. (He called it the "generalized Bondi-Metzner group", but we have since added his name to get to "Bondi-Metzner-Sachs group".) The idea is that the BMS group is an asymptotic symmetry of the metric in an asymptotically flat spacetime. Sachs quotes ...
