functor
English
Etymology
From function, modeled after factor.
Pronunciation
- (Received Pronunciation) IPA(key): /?f??kt?/
Noun
functor (plural functors)
- (grammar) A function word.
- (object-oriented programming) A function object.
- (category theory) A category homomorphism; a morphism from a source category to a target category which maps objects to objects and arrows to arrows, in such a way as to preserve domains and codomains (of the arrows) as well as composition and identities.
- Hyponym: endofunctor

- Given a homotopical category and a functor , a homotopical -colimit (resp. -limit) functor on will be a homotopically terminal (resp. initial) Kan extension of the identity (50.2) along the induced diagram functor (47.1).

- In this chapter, we recall the definition of the category of -objects and we review the relationship between -objects and functors. In short, a -object (in English words, a symmetric sequence of objects, or simply a symmetric object) is the coefficient sequence of a generalized symmetric functor , defined by a formula of the form
