Nuprl Lemma : satisfies-integer-equality_wf
∀[xs,as:ℤ List]. (xs ⋅ as =0 ∈ ℙ)
Proof
Definitions occuring in Statement :
satisfies-integer-equality: xs ⋅ as =0,
list: T List,
uall: ∀[x:A]. B[x],
prop: ℙ,
member: t ∈ T,
int: ℤ
Definitions unfolded in proof :
uall: ∀[x:A]. B[x],
member: t ∈ T,
satisfies-integer-equality: xs ⋅ as =0,
prop: ℙ,
and: P ∧ Q,
subtype_rel: A ⊆r B,
uimplies: b supposing a
