Statement

Setting (p. 3). A Polignac number is a positive even number 2k2k with pn+1−pn=2kp_{n+1}-p_n=2k for infinitely many nn (Definition 1, p. 3; see Theorem 1).

Theorem 2 (p. 3, quoted). "There exists an ineffective constant C′C' such that every interval of type [M,M+C′][M,M+C'] contains at least one Polignac number."

Polignac numbers here are strong Polignac numbers (Remark, p. 3).

Proof pointer

Pages 9--10. By contradiction: if the theorem fails, there are intervals Iν=[Mν,Mν+Cν]I_\nu=[M_\nu,M_\nu+C_\nu] with Mν>Cν>4Mν−1M_\nu>C_\nu>4M_{\nu-1} and M1>C0M_1>C_0 that contain no Polignac number (4.4)--(4.5). Choose an admissible kk-tuple with hν∈[Mν+Cν/2,Mν+Cν]h_\nu\in[M_\nu+C_\nu/2,M_\nu+C_\nu], k≥k0k\ge k_0; every difference hμ−hνh_\mu-h_\nu, ν<μ\nu<\mu, then lies in IμI_\mu (4.8). The Main Theorem makes some such difference a gap between consecutive primes infinitely often (the paper writes "can be written as a difference of two consecutive primes", p. 10), a contradiction. The paper notes that the resulting constant is ineffective (p. 9).

Read depth

Claims checked: the statement was read clause by clause on the printed pages of arXiv:1305.6289v1, and the proof on pp. 9--10 was followed. Nothing here is independently reviewed.
