A proposal of quasi-local mass for 2-surfaces of timelike mean curvature
Bowen Zhao, Shing-Tung Yau, Lars Andersson
A quasi-local mass, typically defined as an integral over a spacelike -surface , should encode information about the gravitational field within a finite, extended region boun…

Strong field behavior of Wang-Yau Quasi-local energy
Bowen Zhao, Lars Andersson, Shing-Tung Yau
We look at the strong field behavior of the Wang-Yau quasi-local energy. In particular, we examine the limit of the Wang-Yau quasi-local energy as the defining spacelike -surfac…

Some Remarks on Wang-Yau Quasi-Local Mass
Bowen Zhao, Lars Andersson, Shing-Tung Yau
We review Wang-Yau quasi-local definitions along the line of gravitational Hamiltonian. This makes clear the connection and difference between Wang-Yau definition and Brown-York or…
