Category of Functors
|
||
|
------------------------
|
||
|
|
||
|
If \\(\\C\\) is _small_ (\\(\\hom{\\C}\\) is a set).
|
||
|
All functors from \\(\\C\\) to some category \\(\\D\\)
|
||
|
form the category \\(\\mathrm{Func}(\\C,\\D)\\).
|
||
|
|
||
|
- \\(\\ob{\\mathrm{Func}(\\C,\\D)}\\): Functors \\(F:\\C→\\D\\)
|
||
|
- \\(\\hom{\\mathrm{Func}(\\C,\\D)}\\): _natural transformations_
|
||
|
- ∘: Functor composition
|
||
|
|
||
|
\\(\\mathrm{Func}(\\C,\\C)\\) is the category of endofunctors of \\(\\C\\).
