Cohomology of a smooth manifold can be computed by solving certain differential equations, or by combinatorially approximating the manifold with a cover as shown with the tribar. Further, it plays a necessary role in Penrose's Twistor theory. Both mathematical approaches are demonstrated in the book by Bott and Tu: | |||
