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: ℙ,
so_apply: x[s],
member: t ∈ T,
set: {x:A| B[x]} ,
function: x:A ⟶ B[x],
equal: s = 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: ℙ,
cand: A c∧ B,
so_apply: x[s],
es-locl: (e <loc e'),
and: P ∧ Q,
subtype_rel: A ⊆r B
