摘要
在广义相对论的远平行等价中,渐近平坦引力场的能量密度可自然定义为限制于三维类空超曲面上的标量密度。该标量密度用挠率张量的迹表达形式简单。此处我们得到 Kerr 黑洞定域化能量的形式表达式。在小的 (比角动量)极限下,可显式计算常量半径曲面内的能量。该表达式恰好与 Brown 和 York 最近提出的方法所得结果相同。

11 pages, Latex file, no figures. The calculation of the energy inside a surface of constant radius, in the limit of small specific angular momentum $a$, has been improved. We arrive exactly at the known expression without expanding the square root which appears in the expression of the energy
