Nuprl Lemma : dlattice-order_wf
∀[X:Type]. ∀[as,bs:X List List]. (as ⇒ bs ∈ ℙ)
Proof
Definitions occuring in Statement :
dlattice-order: as ⇒ bs,
list: T List,
uall: ∀[x:A]. B[x],
prop: ℙ,
member: t ∈ T,
universe: Type
Definitions unfolded in proof :
uall: ∀[x:A]. B[x],
member: t ∈ T,
dlattice-order: as ⇒ bs,
so_lambda: λ2x.t[x],
prop: ℙ,
so_apply: x[s]
