Kartik Prabhu1, ∗ and Ibrahim Shehzad2, † 1Department of Physics, University of California, Santa Barbara, CA 93106, USA 2Department of Physics, Cornell University, Ithaca, NY 14853, USA Abstract We show that the asymptotic charges associated with Lorentz symmetries on past and future null infinity match in the limit to spatial infinity in a class of spacetimes that are asymptotically-flat in the sense of Ashtekar and Hansen. Combined with the results of [1], this shows that all BondiMetzner…
