Supertranslations at timelike infinity
Supertranslations at timelike infinity
A bstract We propose a definition of asymptotic flatness at timelike infinity in four spacetime dimensions. We present a detailed study of the asymptotic equations of motion and the action of supertranslations on asymptotic fields. We show that the Lee-Wald symplectic form Ω( g, δ 1 g , δ 2 …
