WebJan 1, 2024 · The Lorentz group part acts as the global conformal group on the celestial sphere. One may then further enlarge this group, by allowing the full local conformal symmetry of the celestial sphere, this is where superrotations come into play. So by the usual definitions the standard BMS group still does not have the superrotations. … WebAbstract.

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 ...
