Nuprl Lemma : decidable__es-p-local-pred
∀es:EO. ∀[P:E ⟶ ℙ]. ((∀e:E. Dec(P e)) ⇒ (∀e,e':E. Dec(es-p-local-pred(es;P) e e')))
Proof
Definitions occuring in Statement :
es-p-local-pred: es-p-local-pred(es;P),
es-E: E,
event_ordering: EO,
decidable: Dec(P),
uall: ∀[x:A]. B[x],
prop: ℙ,
all: ∀x:A. B[x],
implies: P ⇒ Q,
apply: f a,
function: x:A ⟶ B[x]
Definitions unfolded in proof :
es-p-local-pred: es-p-local-pred(es;P),
all: ∀x:A. B[x],
uall: ∀[x:A]. B[x],
implies: P ⇒ Q,
member: t ∈ T,
prop: ℙ,
so_lambda: λ2x.t[x],
so_apply: x[s],
alle-lt: ∀e<e'.P[e],
and: P ∧ Q,
cand: A c∧ B,
alle-at: ∀e@i.P[e]
