Nuprl Lemma : assert-eq-lnk
∀[a,b:IdLnk]. uiff(↑a = b;a = b ∈ IdLnk)
Proof
Definitions occuring in Statement :
eq_lnk: a = b,
IdLnk: IdLnk,
assert: ↑b,
uiff: uiff(P;Q),
uall: ∀[x:A]. B[x],
equal: s = t ∈ T
Definitions unfolded in proof :
uall: ∀[x:A]. B[x],
member: t ∈ T,
eq_lnk: a = b,
all: ∀x:A. B[x],
implies: P ⇒ Q,
uiff: uiff(P;Q),
and: P ∧ Q,
uimplies: b supposing a,
prop: ℙ,
iff: P ⇐⇒ Q,
rev_implies: P ⇐ Q,
eqof: eqof(d)
Latex:
\mforall{}[a,b:IdLnk]. uiff(\muparrow{}a = b;a = b)
