Nuprl Lemma : nat-trans-equal
∀[C,D:SmallCategory]. ∀[F,G:Functor(C;D)]. ∀[A:nat-trans(C;D;F;G)]. ∀[B:A:cat-ob(C) ⟶ (cat-arrow(D) (F A) (G A))].
A = B ∈ nat-trans(C;D;F;G) supposing A = B ∈ (A:cat-ob(C) ⟶ (cat-arrow(D) (F A) (G A)))
Proof
Definitions occuring in Statement :
nat-trans: nat-trans(C;D;F;G),
functor-ob: ob(F),
cat-functor: Functor(C1;C2),
cat-arrow: cat-arrow(C),
cat-ob: cat-ob(C),
small-category: SmallCategory,
uimplies: b supposing a,
uall: ∀[x:A]. B[x],
apply: f a,
function: x:A ⟶ B[x],
equal: s = t ∈ T
Definitions unfolded in proof :
prop: ℙ,
all: ∀x:A. B[x],
so_apply: x[s],
so_lambda: λ2x.t[x],
nat-trans: nat-trans(C;D;F;G),
uimplies: b supposing a,
member: t ∈ T,
uall: ∀[x:A]. B[x]
