A modification of the Chen-Nester quasilocal expressions
arXiv:gr-qc/0605149 · doi:10.1142/S0218271807010444
Abstract
Chen and Nester proposed four boundary expressions for the quasilocal quantities using the covariant Hamiltonian formalism. Based on these four expressions, there is a simple generalization that one can consider, so that a two parameter set of boundary expressions can be constructed. Using these modified expressions, a nice result for gravitational energy-momentum can be obtained in holonomic frames.
