...A complex is a mathematical structure that combines simplexes and the way they are glued together, and can be considered as a structure on a polyhedron. The field that uses this structure to study the topological properties of polyhedra is called combinatorial topology, or PL topology (piecewise linear topology). Polyhedra whose complex structures are isomorphic are homeomorphic. ... *Some of the terminology that mentions "piecewise linear topology" is listed below.
