Nuprl Lemma : uorder_wf
∀[T:Type]. ∀[R:T ⟶ T ⟶ ℙ]. (UniformOrder(T;x,y.R[x;y]) ∈ ℙ)
Proof
Definitions occuring in Statement :
uorder: UniformOrder(T;x,y.R[x; y]),
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 :
uall: ∀[x:A]. B[x],
member: t ∈ T,
uorder: UniformOrder(T;x,y.R[x; y]),
prop: ℙ,
and: P ∧ Q,
so_lambda: λ2x y.t[x; y],
so_apply: x[s1;s2]
