A characterization of spherical polyhedron surfaces
Feng Luo
A spherical polyhedron surface is a triangulated surface obtained by isometric gluing of spherical triangles. For instance, the boundary of a generic convex polytope in the 3-spher…

A combinatorial curvature flow for compact 3-manifolds with boundary
Feng Luo
We introduce a combinatorial curvature flow for PL metrics on compact triangulated 3-manifolds with boundary consisting of surfaces of negative Euler characteristic. The flow tends…
