Numerical parameters for the simultaneous direction count

The final steps in §6: a fixed polynomial times a Gaussian tail is below any prescribed exponential budget, and the chosen direction bound has the required factor-one-hundred margin.

  1. theorem OAI.LipschitzHilbert.polynomial_gaussian_le_exponential line 23

    Source documentation

    An explicit sufficient lower bound for the count-exception budget.

        (hC : 0 < C) (hc : 0 < c) (hL : 1 ≤ L)
        (hlarge : (|Real.log C| + |a| + J) / c ≤ L) :
        C * L ^ a * Real.exp (-c * L ^ 2) ≤ Real.exp (-J * L) := by
    …
  2. theorem OAI.LipschitzHilbert.eventually_polynomial_gaussian_le_exponential line 54

    Source documentation

    The exceptional budget holds for all sufficiently large L, with no dependence on the number of tops or scales.

        (hC : 0 < C) (hc : 0 < c) :
        ∀ᶠ L : ℝ in atTop, C * L ^ a * Real.exp (-c * L ^ 2) ≤ Real.exp (-J * L) := by

  3. theorem OAI.LipschitzHilbert.count_threshold_product line 62

    Source documentation

    theta=L^(-a) and Lambda=L^(a+2) give the exact quadratic tail.

    theorem count_threshold_product {L : ℝ} (hL : 0 < L) (a : ℝ) :
        L ^ (-a) * L ^ (a + 2) = L ^ 2 := by

  4. theorem OAI.LipschitzHilbert.count_direction_margin line 70

    Source documentation

    The manuscript's D=L^(a+4) absorbs the count threshold and the reference direction with the stated factor-one-hundred margin.

    theorem count_direction_margin {L a : ℝ} (hL : 15 ≤ L) (ha : 0 ≤ a) :
        1 + L ^ (a + 2) ≤ L ^ (a + 4) / 100 := by

  5. theorem OAI.LipschitzHilbert.count_power_budget line 88

    Source documentation

    With K=L^k, P=L^p, p≥k, theta=L^(-a) and lambda=L^(a+2), the complete reference-family prefactor is absorbed by the exact Gaussian rate supplied by angular counting.
