Nuprl Lemma : bounded-relation_wf
∀[R:Set{i:l} ⟶ Set{i:l} ⟶ ℙ']. (Bounded(x,a.R[x;a]) ∈ ℙ')
Proof
Definitions occuring in Statement :
bounded-relation: Bounded(x,a.R[x; a]),
Set: Set{i:l},
uall: ∀[x:A]. B[x],
prop: ℙ,
so_apply: x[s1;s2],
member: t ∈ T,
function: x:A ⟶ B[x]
Definitions unfolded in proof :
rev_implies: P ⇐ Q,
exists: ∃x:A. B[x],
iff: P ⇐⇒ Q,
all: ∀x:A. B[x],
so_apply: x[s],
so_apply: x[s1;s2],
implies: P ⇒ Q,
so_lambda: λ2x.t[x],
and: P ∧ Q,
prop: ℙ,
bounded-relation: Bounded(x,a.R[x; a]),
member: t ∈ T,
uall: ∀[x:A]. B[x]
