Nuprl Lemma : MultiTree_wf
∀[T:Type]. (MultiTree(T) ∈ Type)
Proof
Definitions occuring in Statement :
MultiTree: MultiTree(T),
uall: ∀[x:A]. B[x],
member: t ∈ T,
universe: Type
Definitions unfolded in proof :
uall: ∀[x:A]. B[x],
member: t ∈ T,
MultiTree: MultiTree(T),
uimplies: b supposing a,
nat: ℕ,
so_lambda: λ2x.t[x],
so_apply: x[s],
prop: ℙ
