Nuprl Lemma : eclass-compose3_wf
∀[Info,A,B,C,D:Type]. ∀[f:bag(A) ⟶ bag(B) ⟶ bag(C) ⟶ bag(D)]. ∀[X:EClass(A)]. ∀[Y:EClass(B)]. ∀[Z:EClass(C)].
(eclass-compose3(f;X;Y;Z) ∈ EClass(D))
Proof
Definitions occuring in Statement :
eclass-compose3: eclass-compose3(f;X;Y;Z),
eclass: EClass(A[eo; e]),
uall: ∀[x:A]. B[x],
member: t ∈ T,
function: x:A ⟶ B[x],
universe: Type,
bag: bag(T)
Definitions unfolded in proof :
eclass: EClass(A[eo; e]),
uall: ∀[x:A]. B[x],
member: t ∈ T,
eclass-compose3: eclass-compose3(f;X;Y;Z),
subtype_rel: A ⊆r B
Latex:
