Nuprl Lemma : sq_stable__ip-congruent

∀[rv:InnerProductSpace]. ∀[a,b,c,d:Point].  SqStable(ab=cd)


Proof




Definitions occuring in Statement :  ip-congruent: ab=cd,  inner-product-space: InnerProductSpace,  ss-point: Point,  sq_stable: SqStable(P),  uall: ∀[x:A]. B[x]
Definitions unfolded in proof :  uall: ∀[x:A]. B[x],  member: t ∈ T,  ip-congruent: ab=cd,  subtype_rel: A ⊆r B,  and: P ∧ Q,  prop: ℙ,  sq_stable: SqStable(P),  implies: P ⇒ Q,  guard: {T},  uimplies: b supposing a
