Supports of retained and newly added prime subsets

  1. theorem OAI.JointDickman.remainingSubsetMass_eq_zero line 12
  2. theorem OAI.JointDickman.no_high_changes_retained_added line 23

    Source documentation

    No high coefficient changes force all old high coefficient primes to be kept and prohibit any high additions.

    theorem no_high_changes_retained_added {A R I U : Finset ℕ} {Y : ℝ}
        (hd : Disjoint A R) (hI : I ⊆ A) (hU : U ⊆ R)
        (hno : ∀ p ∈ symmDiff A (I ∪ U), Real.log p ≤ Y) :
        highPrimePart Y I = highPrimePart Y A ∧ highPrimePart Y U = ∅ := by

  3. theorem OAI.JointDickman.addition_product_log_large line 51

    Source documentation

    A newly added prime in the top half of the shell forces the whole addition product to have logarithm greater than Y/2.

    theorem addition_product_log_large {P A I U : Finset ℕ} {Y : ℝ}
        (hP : ∀ p ∈ P, p.Prime) (hU : U ⊆ P)
        (hadd : ∃ p ∈ (I ∪ U) \ A, Y / 2 < Real.log p) (hI : I ⊆ A) :
        Y / 2 < Real.log (∏ p ∈ U, p : ℕ) := by
