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
