Conserved charges of the extended Bondi-Metzner-Sachs algebra
Conserved charges of the extended Bondi-Metzner-Sachs algebra
Isolated objects in asymptotically flat spacetimes in general relativity are characterized by their conserved charges associated with the Bondi-Metzner-Sachs (BMS) group. These charges include total energy, linear momentum, intrinsic angular momentum and center-of-mass location, and, in addition, an infinite number of supermomentum charges associated with supertranslations. Recently, it has been …
