Nuprl Lemma : standard-ds_wf
StandardDS ∈ DS({1..6-})
Proof
Definitions occuring in Statement :
standard-ds: StandardDS,
discrete_struct: DS(A),
int_seg: {i..j-},
member: t ∈ T,
natural_number: $n
Definitions unfolded in proof :
standard-ds: StandardDS,
discrete_struct: DS(A),
member: t ∈ T,
uall: ∀[x:A]. B[x],
int_seg: {i..j-},
all: ∀x:A. B[x],
implies: P ⇒ Q,
bool: 𝔹,
unit: Unit,
it: ⋅,
btrue: tt,
ifthenelse: if b then t else f fi ,
uiff: uiff(P;Q),
and: P ∧ Q,
uimplies: b supposing a,
subtype_rel: A ⊆r B,
bfalse: ff,
exists: ∃x:A. B[x],
prop: ℙ,
or: P ∨ Q,
sq_type: SQType(T),
guard: {T},
bnot: ¬bb,
assert: ↑b,
false: False
