  1. lemma OAI.Problem337.PrimePrefixSize.log_prefix_lower line 10

    Source documentation

    Crossing the square-root cutoff forces a large prefix if the next prime is small.

    lemma log_prefix_lower {d p Y v : ℝ}
        (hd : 0 < d) (hp : 0 < p) (hY : 0 < Y)
        (hYlog : v / 2 ≤ Real.log Y)
        (hcross : Real.sqrt Y < d * p)
        (hplog : Real.log p < v ^ (15 / 16 : ℝ))
        (hsmall : v ^ (15 / 16 : ℝ) ≤ v / 20) :
        v / 5 < Real.log d := by

  5. theorem OAI.Problem337.PrimePrefixSize.eventually_uniform_prefix_large line 67

    Source documentation

    Uniform prefix-size conclusion over all admissible divisor-moment scales.

    theorem eventually_uniform_prefix_large :
        ∀ᶠ S : ℝ in atTop, ∀ v d p Y : ℝ,
          S / (2 * Real.log S) ≤ v →
          0 < d → 0 < p → 0 < Y → v / 2 ≤ Real.log Y →
          Real.sqrt Y < d * p → Real.log p < v ^ (15 / 16 : ℝ) →
          Real.exp (v / 5) < d := by
