Nuprl Lemma : existse-between2_wf

[es:EO]. ∀[e1,e2:E]. ∀[P:{e:E| loc(e) loc(e1) ∈ Id}  ─→ ℙ].  ∃e∈[e1,e2].P[e] ∈ ℙ supposing loc(e2) loc(e1) ∈ Id


Proof




Definitions occuring in Statement :  existse-between2: e∈[e1,e2].P[e] es-loc: loc(e) es-E: E event_ordering: EO Id: Id uimplies: supposing a 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
