Nuprl Lemma : geo-lt_wf
∀[e:BasicGeometry]. ∀[p,q:Length]. (p < q ∈ ℙ)
Proof
Definitions occuring in Statement :
geo-lt: p < q,
geo-length-type: Length,
basic-geometry: BasicGeometry,
uall: ∀[x:A]. B[x],
prop: ℙ,
member: t ∈ T
Definitions unfolded in proof :
so_apply: x[s],
basic-geometry: BasicGeometry,
and: P ∧ Q,
prop: ℙ,
so_lambda: λ2x.t[x],
uimplies: b supposing a,
guard: {T},
subtype_rel: A ⊆r B,
geo-lt: p < q,
member: t ∈ T,
uall: ∀[x:A]. B[x]
