Nuprl Lemma : Message-inhabited
∀[f:Name ⟶ Type]. ↓Message(f) supposing ↓∃h:Name. (↓f h)
Proof
Definitions occuring in Statement :
Message: Message(f),
name: Name,
uimplies: b supposing a,
uall: ∀[x:A]. B[x],
exists: ∃x:A. B[x],
squash: ↓T,
apply: f a,
function: x:A ⟶ B[x],
universe: Type
Definitions unfolded in proof :
uall: ∀[x:A]. B[x],
member: t ∈ T,
uimplies: b supposing a,
squash: ↓T,
exists: ∃x:A. B[x],
prop: ℙ,
so_lambda: λ2x.t[x],
subtype_rel: A ⊆r B,
so_apply: x[s]
Latex:
\mforall{}[f:Name {}\mrightarrow{} Type]. \mdownarrow{}Message(f) supposing \mdownarrow{}\mexists{}h:Name. (\mdownarrow{}f h)
