The quantitative small factors in predictable motion. Fixed powers and constants are absorbed only after the packet and weight estimates.

  2. theorem OAI.LipschitzHilbert.source_predictable_coefficient_le line 35

    Source documentation

    The two summation-by-parts errors have a common inverse-square-root factor as soon as their independent packet and weight bounds do.

  3. theorem OAI.LipschitzHilbert.eventually_source_polynomial_motion line 55

    Source documentation

    Every fixed polynomial prefactor in the exact source motion bounds is dominated by a quarter-power gain of the actual rounded dyadic step.

        ∀ᶠ L : ℝ in atTop,
          C*L^p/Real.sqrt (SourceParameters.step L) ≤
