In geometric topology, PDIFF, for piecewise differentiable, is the category of piecewise-smooth manifolds and piecewise-smooth maps between them. It properly...

isomorphism of PL manifolds is called a PL homeomorphism. PL, or more precisely PDIFF, sits between DIFF (the category of smooth manifolds) and TOP (the category...
