Nuprl Lemma : assert-in-missing-iff
∀i:ℤ. ∀missing:{l:ℤ List| l-ordered(ℤ;x,y.x < y;l)} . (↑in-missing(i;missing) ⇐⇒ (i ∈ missing))
Proof
Definitions occuring in Statement :
in-missing: in-missing(i;missing),
l_member: (x ∈ l),
list: T List,
assert: ↑b,
less_than: a < b,
all: ∀x:A. B[x],
iff: P ⇐⇒ Q,
set: {x:A| B[x]} ,
int: ℤ
Definitions unfolded in proof :
all: ∀x:A. B[x],
iff: P ⇐⇒ Q,
and: P ∧ Q,
implies: P ⇒ Q,
member: t ∈ T,
prop: ℙ,
uall: ∀[x:A]. B[x],
rev_implies: P ⇐ Q,
sq_stable: SqStable(P),
so_lambda: λ2x.t[x],
so_lambda: λ2x y.t[x; y],
so_apply: x[s1;s2],
so_apply: x[s],
false: False,
in-missing: in-missing(i;missing),
top: Top,
uiff: uiff(P;Q),
uimplies: b supposing a,
or: P ∨ Q,
cand: A c∧ B,
decidable: Dec(P),
