Positive energy theorem for asymptotically anti-de Sitter spacetimes with distributional curvature
Yaohua Wang, Xiao Zhang
We establish the positive energy theorem for weak asymptotically anti-de Sitter initial data sets with distributional curvature under the weak dominant energy condition.

Spacelike hypersurfaces with negative total energy in de Sitter spacetime
Zhuobin Liang, Xiao Zhang
De Sitter spacetime can be separated into two parts along two kinds of hypersurfaces and the half-de Sitter spacetimes are covered by the planar and hyperbolic coordinates respecti…

Dirac Operator on Embedded Hypersurfaces
Oussama Hijazi, Sebastian Montiel, Xiao Zhang
New extrinsic lower bounds are given for the classical Dirac operator on the boundary of a compact domain of a spin manifold. The main tool is to solve some boundary problems for t…
