Spherical complexes and radial projections of polytopes
- 93 Downloads
Using the techniques of Gale diagrams a simple criterion is given for determining when a given spherical complex onS n−1 ⊂E n is the radial projection, from the centre ofS n−1, of a convex polytope. Previously a criterion was known only for the casen=2.
