Nuprl Lemma : id-sdata-not-pair
∀[a:Id]. ∀[d1,d2:SecurityData]. uiff(data(a) = <d1, d2> ∈ SecurityData;False)
Proof
Definitions occuring in Statement :
sdata-pair: <d1, d2>,
id-sdata: data(x),
sdata: SecurityData,
Id: Id,
uiff: uiff(P;Q),
uall: ∀[x:A]. B[x],
false: False,
equal: s = t ∈ T
Definitions unfolded in proof :
uall: ∀[x:A]. B[x],
member: t ∈ T,
uiff: uiff(P;Q),
and: P ∧ Q,
uimplies: b supposing a,
false: False,
all: ∀x:A. B[x],
top: Top,
not: ¬A,
implies: P ⇒ Q,
prop: ℙ
Latex:
\mforall{}[a:Id]. \mforall{}[d1,d2:SecurityData]. uiff(data(a) = <d1, d2>False)
