Positivity and Hoop Properties for Chen-Nester-Tung Quasi-local Energy with Analytic Reference in Spherical Symmetry
摘要：
在球对称条件下，利用解析参照，给出了Chen-Nester-Tung准定域能为正的直接证明。还建立了这种能量的一个箍型定理。最后讨论了Chen-Nester-Tung准定域能与Brown-York准定域能之间的关系。
英文摘要：
We provide a direct proof for the positivity of Chen-Nester-Tung quasi-local energy with analytic reference in spherical symmetry. A hoop-type theorem for this energy is also established. Finally, the relation between Chen-Nester-Tung and Brown-York quasi-local energies will be discussed.
