Functor category: Examples, Facts & Definition

In category theory, a branch of mathematics, a functor category D C {\displaystyle D^{C}} is a category where the objects are the functors F : C → D {\displaystyle F:C\to D} and the morphisms are natural transformations η : F → G {\displaystyle \eta :F\to G} between the functors (here, G : C → D {\displaystyle G:C\to D} is another object in the…
