Nuprl Lemma : int-value-type
value-type(ℤ)
Proof
Definitions occuring in Statement :
value-type: value-type(T),
int: ℤ
Definitions unfolded in proof :
value-type: value-type(T),
uall: ∀[x:A]. B[x],
uimplies: b supposing a,
member: t ∈ T,
sq_stable: SqStable(P),
implies: P ⇒ Q,
all: ∀x:A. B[x],
has-value: (a)↓,
squash: ↓T
