The Asymptotic Structure of Gravity at Spatial Infinity in Four Spacetime Dimensions
The Asymptotic Structure of Gravity at Spatial Infinity in Four Spacetime Dimensions
A review of our results on the asymptotic structure of gravity at spatial infinity in four spacetime dimensions is given. Finiteness of the action and integrability of the asymptotic Lorentz boost generators are key criteria that we implement through appropriate boundary conditions. These conditions are `twisted parity conditions', expressing that …
