| Apr 14, 2020 at 4:14 | comment | added | Jochen Glueck | @WlodAA: It seems, though, that the OP considers only compacts sets $K$. | |
| Apr 13, 2020 at 22:24 | comment | added | Wlod AA | Consider $\ J:=(0;1)\subseteq\Bbb R.\ $ Then the sigma closure is $\ J;\ $ it is not the closure, i.e. $\ [0;1].$ | |
