WebbAbstract : Besides simplices, n-cubes form an important class of simple polyhedra. Unlike hyperbolic Coxeter simplices, hyperbolic Coxeter n-cubes are not classified. In this work, we first show that there are no Coxeter n-cubes in Hn for n≥10. Then, we show that the ideal ones exist only for n=2 and 3, and provide a classification. Webb24 juni 2024 · We equip with a membership predicate stating that, given and , we have if and only if satisfies the system of inequalities represented by .Two H-polyhedra are equivalent when they correspond to the same solution set, i.e. their membership predicate agree. We prove that this equivalence relation is decidable, by exploiting the …
Webbdescribe two concrete non-triangulable polyhedra which can be tiled with tetrahedra. From observations made about the provided non-triangulable polyhedra, we started to systematically study extensions of surface triangulations of convex polyhedra. Among others we proved that if each vertex of a convex polyhedron is adjacent to no more than ii WebbP is a polyhedron, since P= {x∈Rn Ax˜ ≤b˜}for some A˜ and b˜.
