Cohomology with compact support - Wikipedia

    https://en.wikipedia.org/wiki/Cohomology_with_compact_support
    called the long exact sequence of cohomology with compact support. It has numerous applications, such as the Jordan curve theorem, which is obtained for X = R² and Z a simple closed curve in X. De Rham cohomology with compact support satisfies a covariant Mayer–Vietoris sequence: if U and V are open sets covering X, then

Group cohomology with compact support - MathOverflow

    https://mathoverflow.net/questions/59017/group-cohomology-with-compact-support
    This response is a little late, but I have thought about the same question recently. I don't think there is a way to define cohomology with compact support in a purely group theoretic way. The problem is that compact cohomology will distinguish between multiple cusps, but cocycles can only capture one cusp.

De Rham cohomology - Wikipedia

    https://en.wikipedia.org/wiki/De_Rham_cohomology
    In mathematics, de Rham cohomology (after Georges de Rham) is a tool belonging both to algebraic topology and to differential topology, capable of expressing basic topological information about smooth manifolds in a form particularly adapted to computation and the concrete representation of cohomology classes.It is a cohomology theory based on the existence of differential forms with ...

algebraic topology - cohomology with compact support ...

    https://math.stackexchange.com/questions/39214/cohomology-with-compact-support
    Furthermore, on any (connected orientable) manifold, closed or not, Poincare duality is true when expressed as a duality between cohomology and cohomology with compact support in the complementary dimension. Thus cohomology with compact support is a natural tool when working with non-closed manifolds.

Kähler differential - Wikipedia

    https://en.wikipedia.org/wiki/Algebraic_de_Rham_cohomology
    The hypercohomology of the de Rham complex of sheaves is called the algebraic de Rham cohomology of X over Y and is denoted by (/) or just () if Y is clear from the context. (In many situations, Y is the spectrum of a field of characteristic zero.) Algebraic de Rham cohomology was introduced by Grothendieck (1966).

    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 …
