Rigidity of Ball-polyhedra via Truncated Voronoi and Delaunay Complexes
Károly Bezdek, Márton Naszódi · 2012
A ball-polyhedron is the intersection with non-empty interior of finitely many (closed) unit balls in Euclidean 3-space. A new result of this paper is a Cauchy-type rigidity theorem for ball-polyhedra. Its proof presented here is based on the underlying truncated Voronoi and Delaunay complexes of ball-polyhedra.
