广义相对论中的准定域质量

Quasilocal mass in general relativity

Mu-Tao Wang, Shing-Tung Yau

摘要:

有许多尝试定义的概念,拟局域质量的类空2-曲面在时空中的哈密顿-雅可比分析。这种方法的主要困难是确定从物理哈密顿量中减去的背景组态的正确选择。对于一般时空中的表面,准局部质量应该是非负的,而对于平坦时空中的表面,准局部质量应该是零。本文提出了规范无关准定域质量的一个新定义,并证明了它具有所需的性质。

英文摘要:

There have been many attempts to define the notion of quasilocal mass for a spacelike 2-surface in spacetime by the Hamilton-Jacobi analysis. The essential difficulty in this approach is to identify the right choice of the background configuration to be subtracted from the physical Hamiltonian. Quasilocal mass should be nonnegative for surfaces in general spacetime and zero for surfaces in flat spacetime. In this letter, we propose a new definition of gauge-independent quasilocal mass and prove that it has the desired properties.
