The finite-summand reduction follows from Dirichlet's theorem and the Chinese remainder theorem.

  1. theorem OAI.Ostmann.not_eventuallyPrimeSumset_of_finite_left line 13

    Source documentation

    A finite nontrivial summand is incompatible with eventual equality to the primes. The only analytic input is Dirichlet's theorem for one reduced residue class, provided by Nat.forall_exists_prime_gt_and_modEq.

    theorem not_eventuallyPrimeSumset_of_finite_left {A B : Set ℕ}
        (hA : A.Nontrivial) (hfin : A.Finite) : ¬ EventuallyPrimeSumset A B := by

    Source documentation

    The finite-summand reduction is symmetric.

  3. theorem OAI.Ostmann.infinite_summands line 25

    Source documentation

    Lemma 2.2: both summands of an eventual decomposition are infinite.

    theorem infinite_summands {A B : Set ℕ} (hA : A.Nontrivial) (hB : B.Nontrivial)
        (h : EventuallyPrimeSumset A B) : A.Infinite ∧ B.Infinite := by
