Rigidity of spacelike hypersurface with constant curvature and intersection angle condition
Shanze Gao
In the Minkowski space, we consider a compact, spacelike hypersurface with boundary, which can be written as a graph on a spacelike hyperplane. We prove that, if its -th mean cu…

Convex spacelike hypersurface of constant curvature with boundary on a hyperboloid
Shanze Gao
We consider convex, spacelike hypersurfaces with boundaries on some hyperboloid (or lightcone) in the Minkowski space. If the hypersurface has constant higher order mean curvature,…
