Let J, g : C D be morphisms of a category . For each X in

Question:

Let J, g : C → D be morphisms of a category ℓ. For each X in ℓ let (a) Eq( - ,∫,g) is a contra variant functor from ℓ to the category of sets.

(b) A morphism i: K → C is a difference kernel of (f,g) if and only if Eq(- ,→,g) is representable with representing object K (that is, there is a natural isomorphism τ: hom_ℓ(-,K) → Eq(- ,∫,g)).
