Webb6 dec. 2024 · A polyhedron (beware remark ) is a topological spacemade up of very simple bits ‘glued’ together. The ‘bits’ are simplicesof different dimensions. An abstract simplicial complexis a neat combinatorial way of giving the corresponding ‘gluing’ instructions, a bit like the plan of a construction kit! Definition Webb4 feb. 2024 · A polyhedron is a convex set, with boundary made up of ‘‘flat’’ boundaries (the technical term is facet). Each facet corresponds to one of the hyperplanes defined by . The vectors are orthogonals to the facets, and point outside the polyhedra. Note that not every set with flat boundaries can be represented as a polyhedron: the set has ...
