Did you know?
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 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. …
WebWe formulate assumptions and definitions such that the five infinities share a single Bondi-Metzner-Sachs (BMS) group of asymptotic symmetries and associated charges. We show how individual ingoing/outgoing massive bodies may be ascribed initial/final BMS charges and derive global conservation laws stating that the change in total charge is ...
