| May 6, 2019 at 9:54 | comment | added | Victor TC | @Fernando I apologize, I meant the coequalizer when the commutative ring is a field. | |
| May 6, 2019 at 9:35 | comment | added | Fernando Muro | @VictorTC equalizers (and limits in general) are easy. The equalizer of two maps is just the kernel of the difference. | |
| May 6, 2019 at 8:19 | comment | added | Victor TC | @Fernando is it also complicated to construct equalizers when the commutative ring is a field?. | |

| Apr 23, 2013 at 20:26 | comment | added | Fernando Muro | That's extremely complicated. There's no explicit way of doing it. The existence of such colimits is via general categorical results which, in my experience, are impossible to trace back in order to recover a sensible construction. | |
