Description

### What is the conjecture

https://www.erdosproblems.com/1040

Let $F\subseteq \mathbb{C}$ be a closed infinite set, and let $\mu(F)$ be the infimum of
$$\lvert \\{ z: \lvert f(z)\rvert < 1\\}\rvert,$$
as $f$ ranges over all polynomials of the shape $\prod (z-z_i)$ with $z_i\in F$.

Is $\mu(F)$ determined by the transfinite diameter of $F$? In particular, is $\mu(F)=0$ whenever the transfinite diameter of $F$ is $\geq 1$?

Status: open

Research direction

Read the linked Erdős Problems page to understand the conjecture, then inspect the repository for existing formalized Erdős problems and their organization. The work is complete when this conjecture is represented as a compiling formal statement in the repository and its meaning matches the source conjecture.
