Corpus analysis for Cohomology
- In this selection, "cohomology" usually appears in the middle of the sentence. The average example has 20.9 words, and this corpus slice is mostly made up of statements.
- Around the word, rham, ordinary, generalized, theory, group and proof stand out and add context to how "cohomology" is used.
- Recognizable usage signals include cohomology arises from and de rham cohomology. That gives this page its own corpus information beyond isolated example sentences.
- By corpus frequency, "cohomology" sits close to words such as aanholt, aardwolf and abati, which helps place it inside the broader word index.
Example types with cohomology
The same corpus examples are grouped by length and sentence type, making it easier to see the contexts in which the word appears:
This gives a homomorphism from de Rham cohomology to singular cohomology. (11 words)
Cohomology arises from the algebraic dualization of the construction of homology. (11 words)
The topological condition is again that the second real cohomology group is trivial. (13 words)
The proof using Stokes's theorem is closely related to the proof using homology (or rather cohomology), because the form ω generates the de Rham cohomology group H n−1 (∂B) used in the cohomology proof. (36 words)
De Rham showed that all of these approaches were interrelated and that, for a closed, oriented manifold, the Betti numbers derived through simplicial homology were the same Betti numbers as those derived through de Rham cohomology. (36 words)
Michael Atiyah and Friedrich Hirzebruch (right), the creators of topological K-theory The Atiyah–Hirzebruch spectral sequence relates the ordinary cohomology of a space to its generalized cohomology theory. (29 words)
