Quasilocal Energy-Momentum for Geometric Gravity Theories
arXiv:gr-qc/9411048 · doi:10.1016/0375-9601(95)92844-T
Abstract
From a covariant Hamiltonian formulation, using symplectic ideas, we obtain covariant quasilocal energy-momentum boundary expressions for general gravity theories. The expressions depend upon which variables are fixed on the boundary, a reference configuration and a displacement vector field. We consider applications to Einstein's theory, black hole thermodynamics and alternate spinor expressions.
