  1. def OAI.QuantitativeVanDerWaerden.CyclicLowerBound line 12

    Source documentation

    One threshold supplies actual avoiding cyclic colorings independently of the eventual number of colors. This is a proposition, not an axiom.

    def CyclicLowerBound (c : ℝ) : Prop :=
    …
  2. theorem OAI.QuantitativeVanDerWaerden.uniform_lower_of_cyclicLowerBound line 18

    Source documentation

    The same cyclic coloring works for every number of digits.

    theorem uniform_lower_of_cyclicLowerBound {c : ℝ} (hcyclic : CyclicLowerBound c) :
        ∃ K : ℕ, ∀ k ≥ K, ∀ r ≥ 2,
          (k : ℝ) ^ (c * k * (Nat.log 2 r : ℝ)) < (W r k : ℝ) := by
    …

  3. theorem OAI.QuantitativeVanDerWaerden.kthRoot_tendsto_of_cyclicLowerBound line 36

    Source documentation

    The fixed-color full limit from a proved cyclic construction.

    theorem kthRoot_tendsto_of_cyclicLowerBound {c : ℝ} (hc : 0 < c)
        (hcyclic : CyclicLowerBound c) {r : ℕ} (hr : 2 ≤ r) :
        Tendsto (fun k : ℕ => (W r k : ℝ) ^ (1 / (k : ℝ))) atTop atTop := by

  4. theorem OAI.QuantitativeVanDerWaerden.length_rate_tendsto_of_cyclicLowerBound line 44

    Source documentation

    The infimum over all color counts retains one absolute threshold.

    theorem length_rate_tendsto_of_cyclicLowerBound {c : ℝ} (hc : 0 < c)
        (hcyclic : CyclicLowerBound c) :
        Tendsto (fun k : ℕ => ⨅ r : {r : ℕ // 2 ≤ r},
          Real.log (W r.val k : ℝ) / ((k : ℝ) * Real.log (r.val : ℝ))) atTop atTop := by
