Deterministic size estimates for the complete remainder of a basic witness.

  1. lemma OAI.TotientAsymptotic.basic_prime_log_le line 13
  2. lemma OAI.TotientAsymptotic.log_suffixPreimage line 23
  3. theorem OAI.TotientAsymptotic.basic_suffix_log_bound line 38

    Source documentation

    All factors after a cutoff are bounded by the first band after it. This keeps the cofactor separate and permits repetitions of the last prime.

    theorem basic_suffix_log_bound {x : ℝ} {H j : ℕ}
        {η : RemainderDatum (L x H)} (hη : IsBasicRemainder x H η) :
        Real.log (suffixPreimage η j : ℝ) ≤
          (L x H-j : ℕ)*Real.exp ((11/10 : ℝ)*bandScale x (j+1))+
            Real.exp (2*bandScale x (L x H)) := by

  5. theorem OAI.TotientAsymptotic.basic_remainder_log_small line 70

    Source documentation

    The total logarithmic size of a basic remainder is uniformly smaller than the largest-prime scale.

    theorem basic_remainder_log_small (H : ℕ) :
        ∀ᶠ x : ℝ in atTop, ∀ η : RemainderDatum (L x H), IsBasicRemainder x H η →
          Real.log (suffixPreimage η 0 : ℝ) ≤ (Real.log x)^(4/5 : ℝ) := by
