Charge and antipodal matching across spatial infinity
Speaker:Kévin Nguyen (King's Coll. London)
Abstract:We derive the antipodal matching relations used to demonstrate the equivalence between soft graviton theorems and BMS charge conservation across spatial infinity. We provide a precise map between Bondi data at null infinity and Beig--Schmidt data at spatial infinity in a context appropriate to the gravitational scattering problem and celestial holography. In addition, we explicitly match the various proposals of BMS charges at null infinity found in the literature with the conserved charges at spatial infinity.
