Nuprl Lemma : alle-between3-false
∀es:EO. ∀e1:E. ∀e2:{e:E| loc(e) = loc(e1) ∈ Id} . (∀e∈(e1,e2].False ⇐⇒ e2 ≤loc e1 )
Proof
Definitions occuring in Statement :
alle-between3: ∀e∈(e1,e2].P[e],
es-le: e ≤loc e' ,
es-loc: loc(e),
es-E: E,
event_ordering: EO,
Id: Id,
all: ∀x:A. B[x],
iff: P ⇐⇒ Q,
false: False,
set: {x:A| B[x]} ,
equal: s = t ∈ T
Definitions unfolded in proof :
alle-between3: ∀e∈(e1,e2].P[e],
all: ∀x:A. B[x],
iff: P ⇐⇒ Q,
and: P ∧ Q,
implies: P ⇒ Q,
member: t ∈ T,
prop: ℙ,
uall: ∀[x:A]. B[x],
so_lambda: λ2x.t[x],
so_apply: x[s],
rev_implies: P ⇐ Q,
false: False,
guard: {T},
uimplies: b supposing a,
decidable: Dec(P),
or: P ∨ Q,
not: ¬A
