Zipper Unfoldability of Domes and Prismoids
Abstract
We study Hamiltonian unfolding-cutting a convex polyhedron along a Hamiltonian path of edges to unfold it without overlap, which could be implemented by a single zipper-of two classes of polyhedra. First we consider domes, which are simple convex polyhedra. We find a series of domes whose graphs are Hamiltonian, yet any Hamiltonian unfolding causes overlap, making the domes Hamiltonian-ununfoldable. Second we turn to prismoids, which are another family of simple convex polyhedra. We show that any nested prismoid is Hamiltonian-unfoldable, and that for general prismoids, Hamiltonian unfoldability can be tested in polynomial time.
