Part 1 - Differential forms and the de Rham cohomology (Paul Harrison) WebHere's Stokes's theorem: ∫ M is in fact a map of cochain complexes. If you want to prove the theorem efficiently, you can use naturality of pullback to reduce to a simpler statement about forms on Δ itself. There will always be a step where you …

WebIf "the de Rham-Weil Theorem" means that you can compute cohomology using acyclic resolutions rather than injective ones, this is a standard result you can find in just about any book on homological algebra. The earliest reference I know is Grothendieck's Tohoku paper, Section 2.4. Share Cite Improve this answer Follow
