In mathematics, a piecewise linear pl manifold is a topological manifold together with a piecewise linear structure on it. A little more precisely it is a space together with a way of identifying it locally with a euclidean space which is compatible on overlaps. All manifolds are topological manifolds by definition, but many manifolds may be. After a line, the circle is the simplest example of a topological manifold.
