| Jul 11, 2017 at 14:27 | comment | added | Jochen Wengenroth | I don't understand your comment. $X=Y$ is clearly Hausdorff. The quotient $Y/\phi(X)$ is Hausdorff if and only if $\phi(X)$ is closed. | |
| Jul 11, 2017 at 12:22 | comment | added | Krzysztof | That's a very nice construction. I did not mention that explicitly but I consider only Hausdorff spaces. Can you see a counterexample with $E$ Hausdorff? | |
