Nuprl Lemma : coset-relation_wf
∀[R:coSet{i:l} ⟶ coSet{i:l} ⟶ ℙ']. (coSetRelation(R) ∈ ℙ')
Proof
Definitions occuring in Statement :
coset-relation: coSetRelation(R),
coSet: coSet{i:l},
uall: ∀[x:A]. B[x],
prop: ℙ,
member: t ∈ T,
function: x:A ⟶ B[x]
Definitions unfolded in proof :
so_apply: x[s],
prop: ℙ,
implies: P ⇒ Q,
so_lambda: λ2x.t[x],
coset-relation: coSetRelation(R),
member: t ∈ T,
uall: ∀[x:A]. B[x]
