A general framework for gravitational charges and holographic renormalization
Venkatesa Chandrasekaran, Eanna E. Flanagan, Ibrahim Shehzad +1
We develop a general framework for constructing charges associated with diffeomorphisms in gravitational theories using covariant phase space techniques. This framework encompasses…
Conservation of asymptotic charges from past to future null infinity: Lorentz charges in general relativity
Kartik Prabhu, Ibrahim Shehzad
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 asymptotically-flat spa…
The Wald-Zoupas prescription for asymptotic charges at null infinity in general relativity
Alexander M. Grant, Kartik Prabhu, Ibrahim Shehzad
We use the formalism developed by Wald and Zoupas to derive explicit covariant expressions for the charges and fluxes associated with the Bondi-Metzner-Sachs symmetries at null inf…
Asymptotic symmetries and charges at spatial infinity in general relativity
Kartik Prabhu, Ibrahim Shehzad
We analyze the asymptotic symmetries and their associated charges at spatial infinity in -dimensional asymptotically-flat spacetimes. We use the covariant formalism of Ashtekar…
Extensions of the asymptotic symmetry algebra of general relativity
Éanna É. Flanagan, Kartik Prabhu, Ibrahim Shehzad
We consider a recently proposed extension of the Bondi-Metzner-Sachs algebra to include arbitrary infinitesimal diffeomorphisms on a (2)-sphere. To realize this extended algebra as…
