Observer dependence of the quasi-local energy and momentum in Schwarzschild space-time
P. P. Yu, R. R. Caldwell
The observer dependence of the quasi-local energy (QLE) and momentum in the Schwarzschild geometry is illustrated. Using the Brown-York prescription, the QLE for families of non-ge…

The limiting behavior of the Liu-Yau quasi-local energy
P. P. Yu
The small- and large-sphere limits of the quasi-local energy recently proposed by Liu and Yau are carefully examined. It is shown that in the small-sphere limit, the non-vacuum lim…
