Erdős Problem #229 — Entire Functions with Prescribed Derivative Zeros

At least 51 years old · documented by

Let (Sn)n∈N(S_n)_{n\in\mathbb{N}} be a sequence of subsets of C\mathbb{C} such that the derived set of each SnS_n is empty, meaning that no SnS_n has a finite limit point. Does there exist a transcendental entire function f:C→Cf:\mathbb{C}\to\mathbb{C} such that, for every integer n≥1n\geq 1, there is an integer k≥0k\geq 0 for which

f(k)(z)=0f^{(k)}(z)=0

for every z∈Snz\in S_n?
