Nuprl Lemma : decidable__alle-le
∀es:EO. ∀e':E. ∀[P:{e:E| loc(e) = loc(e') ∈ Id} ─→ ℙ]. (∀e@loc(e').Dec(P[e]) ⇒ Dec(∀e≤e'.P[e]))
Proof
Definitions occuring in Statement :
alle-le: ∀e≤e'.P[e],
alle-at: ∀e@i.P[e],
es-loc: loc(e),
es-E: E,
event_ordering: EO,
Id: Id,
decidable: Dec(P),
uall: ∀[x:A]. B[x],
prop: ℙ,
so_apply: x[s],
all: ∀x:A. B[x],
implies: P ⇒ Q,
set: {x:A| B[x]} ,
function: x:A ─→ B[x],
equal: s = t ∈ T
