  1. A word.

  2. A object.

  3. A category homomorphism; a morphism from a source category to a target category which maps objects to objects and arrows to arrows (either covariantly or contravariantly), in such a way as to preserve morphism composition and identities. Category:en:Functions

  6. Choosing for U the operation of closure, regularization or relative completion, we obtain from a given functor \mathcal{F}\in\mathcal{JF} the functors
    : \overline{F} : \overrightarrow{X} \rightarrow \overline{F(\overrightarrow{X})}, F^0 : \overrightarrow{X}\rightarrow F(\overrightarrow{X})^0, F^c : \overrightarrow{X} \rightarrow F(\overrightarrow{X})^c.

  9. In this chapter, we recall the definition of the category of \Sigma_*-objects and we review the relationship between \Sigma_*-objects and functors. In short, a \Sigma_*-object (in English words, a symmetric sequence of objects, or simply a symmetric object) is the coefficient sequence of a generalized symmetric functor S(M) : X\rightarrow S(M,X), defined by a formula of the form
    : S(M,X) = \bigoplus^\infty_{r=0} \left ( M(r)\otimes X^{\otimes r}\right )_{\Sigma_r}.
  10. A structure allowing a function to apply within a type, in a way that is conceptually similar to a functor in category theory.
