Editing Generalized function (section)

==Generalized section==
A further way in which the theory has been extended is as '''generalized sections''' of a smooth [[vector bundle]]. This is on the Schwartz pattern, constructing objects dual to the test objects, smooth sections of a bundle that have [[compact support]]. The most developed theory is that of [[De Rham current]]s, dual to [[differential form]]s. These are homological in nature, in the way that differential forms give rise to [[De Rham cohomology]]. They can be used to formulate a very general [[Stokes' theorem]].
