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…

Asymptotic charges for spin-1 and spin-2 fields at the critical sets of null infinity
The asymptotic BMS charges of spin-1 and spin-2 fields are studied near spatial infinity. We evaluate the charges at the critical sets where spatial infinity meets null infinity with the aim of
A general framework for gravitational charges and holographic renormalization
We develop a general framework for constructing charges associated with diffeomorphisms in gravitational theories using covariant phase space techniques. This framework encompasses both localized

A bstractOn any asymptotically-flat spacetime, we show that the asymptotic symmetries and charges of Maxwell fields on past null infinity can be related to those on future null infinity as recently
Properties of spacetimes that are asymptotically flat at timelike infinity
Motivated by recent work by Friedrich (1988) the author studies the class of spacetimes that are asymptotically flat at future null and timelike infinity (AFTI spacetimes). The definition of AFTI
Symmetries and charges of general relativity at null boundaries
A bstractWe study general relativity at a null boundary using the covariant phase space formalism. We define a covariant phase space and compute the algebra of symmetries at the null boundary by
Asymptotic U(1) charges at spatial infinity
A bstractLarge gauge symmetries in Minkowski spacetime are often studied in two distinct regimes: either at asymptotic (past or future) times or at spatial infinity. By working in harmonic gauge, we
On conserved quantities in general relativity
Recently, definitions of total 4‐momentum and angular momentum of isolated gravitating systems have been introduced in terms of the asymptotic behavior of the Weyl curvature (of the underlying
Relaxing the parity conditions of asymptotically flat gravity
Four-dimensional asymptotically flat spacetimes at spatial infinity are defined from first principles without imposing parity conditions or restrictions on the Weyl tensor. The Einstein–Hilbert
Geometry and Physics of Null Infinity
In asymptotically Minkowski space-times, one finds a surprisingly rich interplay between geometry and physics in both the classical and quantum regimes. On the mathematical side it involves null
A unified treatment of null and spatial infinity in general relativity. I - Universal structure, asymptotic symmetries, and conserved quantities at spatial infinity
A new definition of asymptotic flatness in both null and spacelike directions is introduced. Notions relevant to the null regime are borrowed directly from Penrose’s definition of weak asymptotic
