Nuprl Lemma : set-relation-setrel
∀R:coSet{i:l}. SetRelation(setrel(R))
Proof
Definitions occuring in Statement :
setrel: setrel(R),
set-relation: SetRelation(R),
coSet: coSet{i:l},
all: ∀x:A. B[x]
Definitions unfolded in proof :
all: ∀x:A. B[x],
setrel: setrel(R),
set-relation: SetRelation(R),
implies: P ⇒ Q,
member: t ∈ T,
uall: ∀[x:A]. B[x],
subtype_rel: A ⊆r B,
iff: P ⇐⇒ Q,
and: P ∧ Q,
rev_implies: P ⇐ Q,
prop: ℙ
