Nuprl Lemma : rv-0-add
∀[rv:RealVectorSpace]. ∀[x:Point]. x + 0 ≡ x
Proof
Definitions occuring in Statement :
rv-add: x + y,
rv-0: 0,
real-vector-space: RealVectorSpace,
ss-eq: x ≡ y,
ss-point: Point,
uall: ∀[x:A]. B[x]
Definitions unfolded in proof :
rev_uimplies: rev_uimplies(P;Q),
and: P ∧ Q,
uiff: uiff(P;Q),
uimplies: b supposing a,
all: ∀x:A. B[x],
prop: ℙ,
subtype_rel: A ⊆r B,
false: False,
implies: P ⇒ Q,
not: ¬A,
ss-eq: x ≡ y,
member: t ∈ T,
uall: ∀[x:A]. B[x]
