| 2021-05-16 19:46:54 | <gedda> | mniip, thanks for the more proper definition, never saw it as a morhpism between f and fmap f before |
| 2021-05-16 19:47:21 | <mniip> | that's not a correct way to call it |
| 2021-05-16 19:47:44 | <gedda> | yea sorry, between implies iso which is not in this case |
| 2021-05-16 19:47:50 | <mniip> | no |
| 2021-05-16 19:48:21 | <mniip> | saying "f : X -> Y" aka "f is a morphism from X to Y" means that X is an object that is its domain, and Y is an object that is its codomain |
| 2021-05-16 19:48:32 | <mniip> | "f(x) = y" or "f maps x to y" is completely different |
| 2021-05-16 19:48:42 | <mniip> | here x is an element of X (whatever that means) |
