Quasilocal Energy-Momentum for Geometric Gravity Theories

General Relativity and Quantum Cosmology 2009-10-22 v2

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.
