Nuprl Lemma : face-name-eq_wf

[I:Cname List]. ∀[a,b:nameset(I) × ℕ2].  (face-name-eq(a;b) ∈ 𝔹)


Proof




Definitions occuring in Statement :  face-name-eq: face-name-eq(a;b) nameset: nameset(L) coordinate_name: Cname list: List int_seg: {i..j-} bool: 𝔹 uall: [x:A]. B[x] member: t ∈ T product: x:A × B[x] natural_number: $n
Definitions unfolded in proof :  uall: [x:A]. B[x] member: t ∈ T face-name-eq: face-name-eq(a;b) subtype_rel: A ⊆B nameset: nameset(L) coordinate_name: Cname int_upper: {i...} int_seg: {i..j-}
