WebOct 9, 2024 · Hence “presheaf” is a concept with an attitude. Historically, the initial applications of presheaves and sheaves involved cases like S = CRing (the category of commutative rings ), S = Ab ( abelian groups ), S = RMod ( modules ), etc. In category theory, a branch of mathematics, a presheaf on a category is a functor . If is the poset of open sets in a topological space, interpreted as a category, then one recovers the usual notion of presheaf on a topological space. A morphism of presheaves is defined to be a natural transformation of functors. This makes the collection of all presheaves on into a category, and is an example of a functor category.
