Nuprl Lemma : pisend-var_wf
∀[v:pi_prefix()]. pisend-var(v) ∈ Name supposing ↑pisend?(v)
Proof
Definitions occuring in Statement :
pisend-var: pisend-var(v),
pisend?: pisend?(v),
pi_prefix: pi_prefix(),
name: Name,
assert: ↑b,
uimplies: b supposing a,
uall: ∀[x:A]. B[x],
member: t ∈ T
Definitions unfolded in proof :
uall: ∀[x:A]. B[x],
uimplies: b supposing a,
member: t ∈ T,
ext-eq: A ≡ B,
and: P ∧ Q,
subtype_rel: A ⊆r B,
all: ∀x:A. B[x],
implies: P ⇒ Q,
bool: 𝔹,
unit: Unit,
it: ⋅,
btrue: tt,
uiff: uiff(P;Q),
sq_type: SQType(T),
guard: {T},
eq_atom: x =a y,
ifthenelse: if b then t else f fi ,
pisend?: pisend?(v),
pi1: fst(t),
assert: ↑b,
pisend-var: pisend-var(v),
pi2: snd(t),
bfalse: ff,
exists: ∃x:A. B[x],
prop: ℙ,
