Timeline for If the convolution of two functions $f\star g$ is equal to $g$, $f$ is even with compact support and $g$ is bounded, implies that $g$ is constant?

| Apr 24, 2020 at 18:53 | comment | added | Anthony Quas | If the global minimum for $g$ occurs on a set $E$, then write out $f\star g(x)$ for $x\in E$. | |
