Chains of large gaps between primes (1511.04468v1)
Published 13 Nov 2015 in math.NT
Abstract: Let $p_n$ denote the $n$-th prime, and for any $k \geq 1$ and sufficiently large $X$, define the quantity $$ G_k(X) := \max_{p_{n+k} \leq X} \min( p_{n+1}-p_n, \dots, p_{n+k}-p_{n+k-1} ),$$ which measures the occurrence of chains of $k$ consecutive large gaps of primes. Recently, with Green and Konyagin, the authors showed that [ G_1(X) \gg \frac{\log X \log \log X\log\log\log\log X}{\log \log \log X}] for sufficiently large $X$. In this note, we combine the arguments in that paper with the Maier matrix method to show that [ G_k(X) \gg \frac{1}{k2} \frac{\log X \log \log X\log\log\log\log X}{\log \log \log X}] for any fixed $k$ and sufficiently large $X$. The implied constant is effective and independent of $k$.
