Nuprl Lemma : rv-add-sep2
∀rv:RealVectorSpace. ∀x,x',y:Point. (y + x # y + x' ⇒ x # x')
Proof
Definitions occuring in Statement :
rv-add: x + y,
real-vector-space: RealVectorSpace,
ss-sep: x # y,
ss-point: Point,
all: ∀x:A. B[x],
implies: P ⇒ Q
Definitions unfolded in proof :
all: ∀x:A. B[x],
member: t ∈ T,
implies: P ⇒ Q,
prop: ℙ,
uall: ∀[x:A]. B[x],
subtype_rel: A ⊆r B,
or: P ∨ Q,
not: ¬A,
false: False
