Colorings of k-balanced matrices and integer decomposition property of related polyhedra
We show that a class of polyhedra, arising from certain 0, 1 matrices introduced by Truemper and Chandrasekaran, has the integer decomposition property. This is accomplished by pr...

Ununfoldable Polyhedra with Convex Faces
Unfolding a convex polyhedron into a simple planar polygon is a well-studied problem. In this paper, we study the limits of unfoldability by studying nonconvex polyhedra with the ...

Polyhedra genus theorem and Euler formula: A hypermap-formalized intuitionistic proof
This article presents formalized intuitionistic proofs for the polyhedra genus theorem, the Euler formula and a sufficient condition of planarity. They are based on a hypermap mod...

An Efficient Method for Computing Exact State Space of Petri Nets With Stopwatches
In this paper, we address the issue of the formal verification of real-time systems in the context of a preemptive scheduling policy. We propose an algorithm which computes the st...

On the infinitesimal rigidity of weakly convex polyhedra
The main motivation here is a question: whether any polyhedron which can be subdivided into convex pieces without adding a vertex, and which has the same vertices as a convex poly...

Validation and Storage of Polyhedra through Constrained Delaunay Tetrahedralization
Abstract. Closed, watertight, 3D geometries are represented by polyhedra. Current data models define these polyhedra basically as a set of polygons, leaving the test on intersectin...

On the Representation of Timed Polyhedra
In this paper we investigate timed polyhedra, i.e. polyhedra which are finite unions of full dimensional simplices of a special kind. Such polyhedra form the basis of timing analys...

Orthogonal Polyhedra: Representation and Computation
Abstract. In this paper we investigate orthogonal polyhedra, i.e. polyhedra which are finite unions of full-dimensional hyper-rectangles. We define representation schemes for the...

Feature-based Surface Decomposition for Correspondence and Morphing Between Polyhedra
We present a new approach for establishing correspondence between two homeomorphic 3D polyhedral models. The user can specify corresponding feature pairs on the polyhedra with a s...
