| Aug 22, 2023 at 21:58 | comment | added | David Roberts♦ | @TianVlašić yes, this is true. But I see I wrote "if...bimorphisms are given by" bijective functions. So it's just a special case. | |
| Aug 22, 2023 at 20:27 | comment | added | Tian Vlašić | @DavidRoberts I don't think bimorphisms of concrete categories are the bijective functions. There a are plenty examples of epimorphisms, say in $\mathbf{Ring}$ that are not surjective. | |

Perhaps I could have worded it: if you want to look at inequivalent topologies on a set, then you can't looks at isomorphism classes, but at bimorphism classes of spaces. | |
