Nuprl Lemma : existse-before_wf

[es:EO]. ∀[e':E]. ∀[P:{e:E| loc(e) loc(e') ∈ Id}  ⟶ ℙ].  (∃e<e'.P[e] ∈ ℙ)


Proof




Definitions occuring in Statement :  existse-before: e<e'.P[e] es-loc: loc(e) es-E: E event_ordering: EO Id: Id uall: [x:A]. B[x] prop: so_apply: x[s] member: t ∈ T set: {x:A| B[x]}  function: x:A ⟶ B[x] equal: t ∈ T
Definitions unfolded in proof :  existse-before: e<e'.P[e] uall: [x:A]. B[x] member: t ∈ T so_lambda: λ2x.t[x] prop: cand: c∧ B so_apply: x[s] es-locl: (e <loc e') and: P ∧ Q subtype_rel: A ⊆B
