  1. theorem OAI.Problem337.DivisorMomentFinalBudget.eventually_sqrt_cutoff_window line 10

    Source documentation

    The square-root cutoff in the harmonic-prefix estimate satisfies the uniform large-class parameter window.

    theorem eventually_sqrt_cutoff_window (D : ℝ) :
        ∀ᶠ S : ℝ in atTop, ∀ v Y : ℝ,
          S / (2 * Real.log S) ≤ v → v ≤ D * S →
          Real.exp (v / 2) ≤ Y → Y ≤ Real.exp v →
          0 ≤ v ∧ 2 ≤ Real.sqrt Y ∧ Real.log (Real.sqrt Y) ≤ D * S := by

  2. theorem OAI.Problem337.DivisorMomentFinalBudget.final_budget_of_large_majorant line 43

    Source documentation

    Final loss absorption with the large-class majorant supplied explicitly. This helper isolates the harmless square-root cutoff and finite-band count from the number-theoretic class estimates.

  3. theorem OAI.Problem337.DivisorMomentFinalBudget.eventually_divisor_moment_final_budget line 70

    Source documentation

    Exact final numerical budget for the large, small, and dyadic intermediate classes. All growth estimates are unconditional and uniform in both windows.
