  1. lemma OAI.Problem337.eventually_log_pow_lt_mul_rpow line 12

    Source documentation

    Any fixed logarithmic power is eventually smaller than an arbitrary positive multiple of a positive real power.

    lemma eventually_log_pow_lt_mul_rpow (n : ℕ) (r c : ℝ) (hr : 0 < r) (hc : 0 < c) :
        ∀ᶠ x : ℝ in atTop, (Real.log x) ^ n < c * x ^ r := by

  2. lemma OAI.Problem337.eventually_exceptional_triples_lt_main_term line 24

    Source documentation

    The exceptional-prime triple estimate is lower order than the quantitative three-prime main term. This is purely an asymptotic comparison, not a three-prime theorem.

    lemma eventually_exceptional_triples_lt_main_term (C c : ℝ) (hC : 0 ≤ C) (hc : 0 < c) :
        ∀ᶠ x : ℝ in atTop,
          C * x ^ (7 / 4 : ℝ) * Real.log x * Real.log (Real.log x) <
            c * x ^ (2 : ℕ) / (Real.log x) ^ 3 := by

  3. lemma OAI.Problem337.eventually_exceptional_prime_triple_count_small line 55

    Source documentation

    Natural-index form targeting a count of exceptional primes: the elementary bound 3 * u * B u for contaminated ordered triples is negligible.

        (hB : ∀ᶠ u : ℕ in atTop,

            Real.log (Real.log (u : ℝ))) :
