本文证明了具有四维等距匹配参考的Chen-Nester-Tung(CNT)准局域能与Wang-Yau(WY)准局域能密切相关。作为一个特殊的例子,我们计算了在明显临界点(0,0)处具有轴对称嵌入的轴对称Kerr类时空的CNT准局域能的第二变分,发现在大多数情况下它是一个鞍临界点.此外,作为副产品,我们将Tam和第一作者Liu和Tam(2016)关于轴对称Kerr类时空的CNT准局域能量和Brown-York质量重合的先前结果推广到一般时空。
In this paper, we show that the Chen-Nester-Tung (CNT) quasi-local energy with 4D isometric matching references is closely related to the Wang–Yau (WY) quasi-local energy. As a particular example, we compute the second variation of the CNT quasi-local energy for axially symmetric Kerr-like spacetimes with axially symmetric embeddings at the obvious critical point (0, 0) and find that it is a saddle critical point in most of the cases. Also, as a byproduct, we generalize a previous result about the coincidence of the CNT quasi-local energy and Brown–York mass for axially symmetric Kerr-like spacetimes by Tam and the first author Liu and Tam (2016) to general spacetimes.
