This PR adds LinearIsometry.completion and LinearIsometry.fromCompletion. These are the LinearIsometry versions of the .completion and .fromCompletion maps, extending a linear isometry f : E →ₛₗᵢ[σ₁₂] F to UniformSpace.Completion E →ₛₗᵢ[σ₁₂] UniformSpace.Completion F and UniformSpace.Completion E →ₛₗᵢ[σ₁₂] F respectively.

Naming scheme is chosen to match with the Zulip thread here and the associated PR #38039.

No toContinuousLinearMap_fromCompletion was added because ContinuousLinearMap.fromCompletion doesn't exist yet.

  • The relative value is the weighted sum of the differences with weight given by the inverse of the current value of the statistic.
  • The absolute value is the relative value divided by the total sum of the inverses of the current values (i.e. the weighted average of the differences).
