Nuprl Lemma : es-first-unique
∀[es:EO]. ∀[e,e':E]. (e = e' ∈ E) supposing ((loc(e) = loc(e') ∈ Id) and (↑first(e')) and (↑first(e)))
Proof
Definitions occuring in Statement :
es-first: first(e),
es-loc: loc(e),
es-E: E,
event_ordering: EO,
Id: Id,
assert: ↑b,
uimplies: b supposing a,
uall: ∀[x:A]. B[x],
equal: s = t ∈ T
