Abstract

In a recent advance towards the Prime kk-tuple Conjecture, Maynard and Tao have shown that if kk is sufficiently large in terms of mm, then for an admissible kk-tuple H(x)={gx+hj}j=1k\mathcal{H}(x) = \{gx + h_j\}_{j=1}^k of linear forms in Z[x]\mathbb{Z}[x], the set H(n)={gn+hj}j=1k\mathcal{H}(n) = \{gn + h_j\}_{j=1}^k contains at least mm primes for infinitely many nNn \in \mathbb{N}. In this note, we deduce that H(n)={gn+hj}j=1k\mathcal{H}(n) = \{gn + h_j\}_{j=1}^k contains at least mm consecutive primes for infinitely many nNn \in \mathbb{N}. We answer an old question of Erd\H os and Tur\'an by producing strings of m+1m + 1 consecutive primes whose successive gaps δ1,,δm\delta_1,\ldots,\delta_m form an increasing (resp. decreasing) sequence. We also show that such strings exist with δj1δj\delta_{j-1} \mid \delta_j for 2jm2 \le j \le m. For any coprime integers aa and DD we find arbitrarily long strings of consecutive primes with bounded gaps in the congruence class amodDa \bmod D.
