Webb24 okt. 2008 · The absolute simplicial approximation theorem, which dates back to Alexander (l), states that there is a simplicial approximation g to any given continuous map f between two finite simplicial complexes (see for instance (2), p. 37 or (3), p. 86). The relative theorem given here permits us to leave f unchanged on any subcomplex, on … Webb2.1. Simplicial covering The following theorem allows us to decompose a polyhedron into oriented tetrahedra. Then we can apply operations to the polyhedron ... As this is a complex operation, we use an approximation. If none of the previous conditions is satisfied then the tetrahedron S is not classified in the tetra-cone ffT ...
