Nuprl Lemma : l-ordered_wf
∀[T:Type]. ∀[L:T List]. ∀[R:T ⟶ T ⟶ ℙ]. (l-ordered(T;x,y.R[x;y];L) ∈ ℙ)
Proof
Definitions occuring in Statement :
l-ordered: l-ordered(T;x,y.R[x; y];L),
list: T List,
uall: ∀[x:A]. B[x],
prop: ℙ,
so_apply: x[s1;s2],
member: t ∈ T,
function: x:A ⟶ B[x],
universe: Type
Definitions unfolded in proof :
l-ordered: l-ordered(T;x,y.R[x; y];L),
uall: ∀[x:A]. B[x],
member: t ∈ T,
so_lambda: λ2x.t[x],
implies: P ⇒ Q,
prop: ℙ,
