The Hamiltonian boundary term and quasi-local energy flux
Chiang-Mei Chen, James M. Nester, Roh-Suan Tung
The Hamiltonian for a gravitating region includes a boundary term which determines not only the quasi-local values but also, via the boundary variation principle, the boundary cond…

Quasi-local energy-momentum and energy flux at null infinity
Xiaoning Wu, Chiang-Mei Chen, James M. Nester
The null infinity limit of the gravitational energy-momentum and energy flux determined by the covariant Hamiltonian quasi-local expressions is evaluated using the NP spin coeffici…
