| Jan 6, 2017 at 11:32 | comment | added | Kevin Buzzard | Oh! Then I am going to go with "I don't know any particular standard terminology for this kind of object" (and I'd suggest that you edit the question, rather than fixing it in the comments). Maybe someone else can suggest something. | |
| Jan 6, 2017 at 11:20 | comment | added | François Durand | Thanks for your suggestion, which makes me realize that I oversimplified a bit my original question. In fact, what I consider exactly is $f_r : X \to Y$ defined by $f_r = f \circ r \circ []$, where the bracket operator takes the equivalence class of an element. For this reason, it seems to me that "restriction" does not convey exactly the notion I'm using. | |
