Nuprl Lemma : lg-exists_wf

[T:Type]. ∀[P:T ⟶ ℙ]. ∀[G:LabeledGraph(T)].  (lg-exists(G;x.P[x]) ∈ ℙ)


Proof




Definitions occuring in Statement :  lg-exists: lg-exists(G;x.P[x]) labeled-graph: LabeledGraph(T) uall: [x:A]. B[x] prop: so_apply: x[s] member: t ∈ T function: x:A ⟶ B[x] universe: Type
Definitions unfolded in proof :  uall: [x:A]. B[x] member: t ∈ T lg-exists: lg-exists(G;x.P[x]) subtype_rel: A ⊆B nat: so_lambda: λ2x.t[x] so_apply: x[s] prop:
