| Mar 12, 2013 at 14:20 | comment | added | H. Shindoh | I see. Do you have any explicit example of your $f$? | |

| Mar 12, 2013 at 14:01 | comment | added | Andrej Bauer | $Z$ is the space of natural numbers with discrete topology. | |
| Mar 12, 2013 at 14:00 | comment | added | Eric Wofsey | $Z$ is just an infinite discrete space. | |
| Mar 12, 2013 at 13:57 | comment | added | H. Shindoh | Can you give me an explicit description of $Z$? | |
