| Aug 5, 2022 at 16:11 | comment | added | Piku | I am very sorry that I forgot to mention $S\subseteq\{z\in\mathbb{C}:\vert z\vert=1\}$ is a compact set such that $\text{conv} S\supseteq\{z\in\mathbb{C}:\vert z\vert\leq\frac{1}{\sqrt{2}}\}$. But I accept that your example answers the question that I have asked in negative. | |
