62Zero morphism — In category theory, a zero morphism is a special kind of morphism exhibiting properties like those to and from a zero object. Suppose C is a category, and f : X → Y is a morphism in C. The morphism f is called a constant morphism (or… …
63Representable functor — In mathematics, especially in category theory, a representable functor is a functor of a special form from an arbitrary category into the category of sets. Such functors give representations of an abstract category in terms of known structures (i …
64Cone (category theory) — In category theory, a branch of mathematics, the cone of a functor is an abstract notion used to define the limit of that functor. Cones make other appearances in category theory as well. Contents 1 Definition 2 Equivalent formulations 3 Category …
