Nuprl Lemma : sq_stble__rv-isometry

[rv:InnerProductSpace]. ∀[f:Point ⟶ Point].  SqStable(Isometry(f))


Proof




Definitions occuring in Statement :  rv-isometry: Isometry(f) inner-product-space: InnerProductSpace ss-point: Point sq_stable: SqStable(P) uall: [x:A]. B[x] function: x:A ⟶ B[x]
Definitions unfolded in proof :  sq_stable: SqStable(P) implies:  Q so_apply: x[s] prop: and: P ∧ Q so_lambda: λ2x.t[x] uimplies: supposing a guard: {T} subtype_rel: A ⊆B member: t ∈ T uall: [x:A]. B[x] rv-isometry: Isometry(f)
