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
### Choose either option

Contributor guide
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.
