Nuprl Lemma : eq_int-wf-partial2
∀[x,y:partial(ℤ)]. ((x =z y) ∈ partial(𝔹))
Proof
Definitions occuring in Statement :
partial: partial(T),
eq_int: (i =z j),
bool: 𝔹,
uall: ∀[x:A]. B[x],
member: t ∈ T,
int: ℤ
Definitions unfolded in proof :
uall: ∀[x:A]. B[x],
member: t ∈ T,
subtype_rel: A ⊆r B,
uimplies: b supposing a
