Nuprl Lemma : isEmpty-nat-missing_wf
∀[s:nat-missing-type()]. (isEmpty-nat-missing(s) ∈ 𝔹)
Proof
Definitions occuring in Statement :
isEmpty-nat-missing: isEmpty-nat-missing(s),
nat-missing-type: nat-missing-type(),
bool: 𝔹,
uall: ∀[x:A]. B[x],
member: t ∈ T
Definitions unfolded in proof :
uall: ∀[x:A]. B[x],
member: t ∈ T,
isEmpty-nat-missing: isEmpty-nat-missing(s),
nat-missing-type: nat-missing-type(),
all: ∀x:A. B[x],
implies: P ⇒ Q,
bool: 𝔹,
unit: Unit,
it: ⋅,
btrue: tt,
band: p ∧b q,
ifthenelse: if b then t else f fi ,
uiff: uiff(P;Q),
and: P ∧ Q,
uimplies: b supposing a,
subtype_rel: A ⊆r B,
top: Top,
bfalse: ff
