- In mathematics, a
pullback is
either of two different, but
related processes:
precomposition and fiber-product. Its dual is a pushforward. Precomposition...

cohomology theory is a grade-preserving R-algebra homomorphism:...
-
coproduct mapping to A, and a
morphism A' → A, the
pullback is an I-indexed
coproduct of the
