Nov 17, 2016 at 23:53 | comment | added | Didi | @NoahSchweber Do you think that it is true for metric space? I would like it were true for compact metric spaces. | |
Nov 17, 2016 at 23:16 | comment | added | Georg Lehner | I misread thinking you meant the line with doubled origin. My bad. | |
Nov 17, 2016 at 23:13 | comment | added | Noah Schweber | @georglehner no, it's indiscrete - every open containing 0 contains a and vice versa. | |
