Nuprl Lemma : int-decr-map-find-wf
∀[Value:Type]. ∀[k:ℤ]. ∀[m:int-decr-map-type(Value)]. (int-decr-map-find(k;m) ∈ Value?)
Proof
Definitions occuring in Statement :
int-decr-map-find: int-decr-map-find(k;m),
int-decr-map-type: int-decr-map-type(Value),
uall: ∀[x:A]. B[x],
unit: Unit,
member: t ∈ T,
union: left + right,
int: ℤ,
universe: Type
Definitions unfolded in proof :
uall: ∀[x:A]. B[x],
member: t ∈ T,
prop: ℙ,
and: P ∧ Q,
int-decr-map-type: int-decr-map-type(Value),
subtype_rel: A ⊆r B,
uimplies: b supposing a,
top: Top,
so_lambda: λ2x.t[x],
all: ∀x:A. B[x],
so_apply: x[s],
implies: P ⇒ Q,
squash: ↓T,
unit: Unit
Latex:
\mforall{}[Value:Type]. \mforall{}[k:\mBbbZ{}]. \mforall{}[m:int-decr-map-type(Value)]. (int-decr-map-find(k;m) \mmember{} Value?)
