Editing Differential form (section)

== History ==
Differential forms are part of the field of differential geometry, influenced by linear algebra.  Although the notion of a differential is quite old, the initial attempt at an algebraic organization of differential forms is usually credited to [[Élie Cartan]] with reference to his 1899 paper.<ref>{{Citation |title=Sur certaines expressions différentielles et le problème de Pfaff | first=Élie  |last=Cartan |journal=Annales Scientifiques de l'École Normale Supérieure |url=http://www.numdam.org/item?id=ASENS_1899_3_16__239_0|year=1899 | volume=16 |pages=239–332| doi=10.24033/asens.467 |doi-access=free }}</ref> Some aspects of the [[exterior algebra]] of differential forms appears in [[Hermann Grassmann]]'s 1844 work, ''Die Lineale<!--sic--> Ausdehnungslehre, ein neuer Zweig der Mathematik (The Theory of Linear Extension, a New Branch of Mathematics)''.
