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...

in turn contained in the category of piecewise-differentiable functions, PDIFF. Important sub-classes of piecewise linear functions include the continuous...
