Nuprl Lemma : vs-neg-add
∀[K:Rng]. ∀[vs:VectorSpace(K)]. ∀[x:Point(vs)]. (-(x) + x = 0 ∈ Point(vs))
Proof
Definitions occuring in Statement :
vs-neg: -(x),
vs-add: x + y,
vs-0: 0,
vector-space: VectorSpace(K),
vs-point: Point(vs),
uall: ∀[x:A]. B[x],
equal: s = t ∈ T,
rng: Rng
Definitions unfolded in proof :
all: ∀x:A. B[x],
implies: P ⇒ Q,
rev_implies: P ⇐ Q,
and: P ∧ Q,
iff: P ⇐⇒ Q,
guard: {T},
uimplies: b supposing a,
subtype_rel: A ⊆r B,
true: True,
rng: Rng,
squash: ↓T,
member: t ∈ T,
uall: ∀[x:A]. B[x]
