Nuprl Lemma : es-knows-knows
∀[poss:EO ─→ ℙ']. ∀[R:PossibleEvent(poss) ─→ PossibleEvent(poss) ─→ ℙ'].
(Trans(PossibleEvent(poss);a,b.R a b)
⇒ (∀[P:PossibleEvent(poss) ─→ ℙ']. ∀e:PossibleEvent(poss). (K(P)@e ⇒ K(λe.K(P)@e)@e)))
Proof
Definitions occuring in Statement :
es-knows: K(P)@e,
possible-event: PossibleEvent(poss),
event_ordering: EO,
trans: Trans(T;x,y.E[x; y]),
uall: ∀[x:A]. B[x],
prop: ℙ,
all: ∀x:A. B[x],
implies: P ⇒ Q,
apply: f a,
lambda: λx.A[x],
function: x:A ─→ B[x]
