Let Cat be the category whose objects are small categories (categories whose collection of objects are sets) and whose morphisms Cat(C,D) from category C to category D are functors F : C → D. Let Set be the category whose objects are sets and given x, y ∈ Ob(Set) morphisms in Set from x to y are maps f : x → y. We define an equivalence relation IsoC on Ob(C) as follows: two objects x and y are ...
