Nuprl Lemma : face-map_wf_fresh-cname

[L:Cname List]. ∀[p:ℕ2].  ((fresh-cname(L):=p) ∈ name-morph(L+;L))


Proof




Definitions occuring in Statement :  face-map: (x:=i) name-morph: name-morph(I;J) add-fresh-cname: I+ fresh-cname: fresh-cname(I) coordinate_name: Cname list: List int_seg: {i..j-} uall: [x:A]. B[x] member: t ∈ T natural_number: $n
Definitions unfolded in proof :  uall: [x:A]. B[x] member: t ∈ T add-fresh-cname: I+ has-value: (a)↓ prop: uimplies: supposing a so_lambda: λ2x.t[x] so_apply: x[s] subtype_rel: A ⊆B
