How this entity was disambiguated
This entity first appeared as the object of triple T23142489 — resolving that mention is where its identity was fixed. The disambiguator weighed these candidate entities and picked the highlighted one (or “None”, minting a new entity). This is how homonymy is resolved: the same surface form can point to different entities.

-
A.
Čech–de Rham complex
The Čech–de Rham complex is a double complex that combines Čech cochains with differential forms to compute de Rham cohomology via open covers.
-
B.
Hodge decomposition
Hodge decomposition is a fundamental result in differential geometry and Hodge theory that expresses differential forms on a Riemannian manifold uniquely as sums of exact, co-exact, and harmonic components.
-
C.
Hodge structure
A Hodge structure is an algebraic structure on the cohomology of complex algebraic varieties that decomposes it into pieces reflecting both complex and topological properties, central to Hodge theory in algebraic geometry.
-
D.
Hodge Laplacian
The Hodge Laplacian is a differential operator on differential forms of a Riemannian manifold that combines the exterior derivative and its adjoint to study harmonic forms and de Rham cohomology.
-
E.
de Rham cohomology
de Rham cohomology is a cohomology theory for smooth manifolds that uses differential forms to capture their global topological and geometric properties.
- F. None of above. chosen
- G. Unsure - the case is ambiguous/there is not enough information to decide.
