Compactly supported cohomology is the cohomology of the complex of compactly supported differential forms (i.e., smooth forms that are zero outside of some compact set).

But we have already seen that for the integration to be defined rigorously we have to stick to compact support differential forms. Surprisingly enough, this restriction leads to another type of cohomology. The restriction of the de Rham complex to compact support differential forms leads to a new complex

on with a proof of de Rham’s theorem, which states that for smooth manifolds singular cohomology is identical to de Rham cohomology. A similar proof is used in chapter 10, where I proved Poincar´e duality, which gives a relation between de Rham cohomology and …

Homotopic smoothe maps induce isomorphic maps in (standard) de Rham cohomology. The same proof is supposed to work also for de Rham with compact support if the two maps are proper and the homotopy between them is smooth and proper.I have an explicit formula for the chain complex homotopy

In compactly supported cohomology cocycles and coboundaries on some space are required to have compact support: to be non-trivial only over a compact subspace/compact subobject of the base.

Corollary 6.6. If M is an n-dimensional manifold with a finite good cover, then its de Rham cohomology groups with compact support are finite dimensional. With this little incentive, we now introduce the notion of cohomology with compact support.
