Energy of Isolated Systems at Retarded Times as the Null Limit of Quasilocal Energy ∗
We define the energy of a perfectly isolated system at a given retarded time as the suitable null limit of the quasilocal energy E. The result coincides with the Bondi-Sachs mass. Our E is the lapse-unity shift-zero boundary value of the gravitational Hamiltonian appropriate for the partial system Σ contained within a finite topologically spherical boundaryB = ∂Σ. Moreover, we show that with an...
متن کاملQuasilocal energy conditions.
The classical value of the Hamiltonian for a system with timelike boundary has been interpreted as a quasilocal energy. This quasilocal energy is not positive definite. However, we derive a ‘quasilocal dominant energy condition’ which is the natural consequence of the local dominant energy condition. We discuss some implications of this quasilocal energy condition. In particular, we find that i...
متن کاملQuasilocal gravitational energy.
Abstract. A dynamically preferred quasi-local definition of gravitational energy is given in terms of the Hamiltonian of a ‘2+2’ formulation of general relativity. The energy is well-defined for any compact orientable spatial 2-surface, and depends on the fundamental forms only. The energy is zero for any surface in flat spacetime, and reduces to the Hawking mass in the absence of shear and twi...
متن کاملQuasilocal Energy in FRW Cosmology
This paper presents a calculation of the quasilocal energy of a generic FRW model of the universe. The results have the correct behavior in the small-sphere limit and vanish for the empty Milne universe. Higher order corrections are found when comparing these results to classical calculations of cosmological energy. This case is different from others in the literature chiefly in that it involve...
متن کاملIs the Hawking Quasilocal Energy "Newtonian"?
The Misner–Sharp–Hernandez mass defined in general relativity and in spherical symmetry has been recognized as having a Newtonian character in previous literature. In order to better understand this feature we relax spherical symmetry and we study the generalization of the Misner–Sharp–Hernandez mass to general spacetimes, i.e., the Hawking quasilocal mass. The latter is decomposed into a matte...
