Asymptotic structure of the null surface formulation and the classical graviton
(2016)
The dynamical equations for the null surface formulation of general relativity for purely radiative spacetimes are derived. Those asymptotically flat spacetimes describe the nonlinear evolution of gravitational radiation ...
Center of mass and spin for isolated sources of gravitational radiation
(2016)
We define the center of mass and spin of an isolated system in general relativity. The resulting relationships between these variables and the total linear and angular momentum of the gravitational system are remarkably ...
