Editing Chern–Simons form (section)

{{Short description|Secondary characteristic classes of 3-manifolds}}
In [[mathematics]], the '''Chern–Simons forms''' are certain secondary [[characteristic class]]es.<ref>{{Cite web|title=Remarks on Chern–Simons theory|url=https://www.ams.org/journals/bull/2009-46-02/S0273-0979-09-01243-9/S0273-0979-09-01243-9.pdf|last=Freed|first=Daniel|date=January 15, 2009|access-date=April 1, 2020}}</ref> The theory is named for [[Shiing-Shen Chern]] and [[James Harris Simons]], co-authors of a 1974 paper entitled "Characteristic Forms and Geometric Invariants," from which the theory arose.<ref>{{Cite book|last1=Chern|first1=Shiing-Shen|url=https://books.google.com/books?id=uOfSa0sfJr0C&q=Characteristic+Forms+and+Geometric+Invariants&pg=PA363|title=A Mathematician and His Mathematical Work: Selected Papers of S.S.
