Query: A note on the positivity of a quasi-local mass in general dimensions   Wang and Yau [10] introduced a quasi-local mass, which is a hyperbolic
background generalization of Liu-Yau's expression [7] [8], and proved its
positivity. In this note, we prove that the positivity of this quasi-local mass
is still valid under weaker assumptions on the boundary hypersurface in general
dimensions. The method we used is similar to that used by Eichmair, Miao and
Wang in [4].
