Topological manifold with a piecewise linear structure on it.
In mathematics, a piecewise linear manifold (PL manifold) is a topological manifold together with a piecewise linear structure on it. Such a structure can be defined by means of an atlas, such that one can pass from chart to chart in it by piecewise linear functions. This is slightly stronger than the topological notion of a triangulation.[a]
An isomorphism of PL manifolds is called a PL homeomorphism.
