Nuprl Lemma : es-first-at-since_wf
∀[es:EO]. ∀[i:Id]. ∀[e':E]. ∀[P,R:{e:E| loc(e) = i ∈ Id} ⟶ ℙ]. (es-first-at-since(es;i;e';e.R[e];e.P[e]) ∈ ℙ)
Proof
Definitions occuring in Statement :
es-first-at-since: es-first-at-since(es;i;e;e.R[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 :
uall: ∀[x:A]. B[x],
member: t ∈ T,
es-first-at-since: es-first-at-since(es;i;e;e.R[e];e.P[e]),
prop: ℙ,
and: P ∧ Q,
cand: A c∧ B,
so_apply: x[s],
subtype_rel: A ⊆r B,
so_lambda: λ2x.t[x],
all: ∀x:A. B[x],
implies: P ⇒ Q,
uimplies: b supposing a,
exists: ∃x:A. B[x]
