| Jun 13, 2017 at 21:50 | comment | added | Jeremy Rickard | @CountDracula Quite right. But finitely generated flat modules over a local ring are projective, which is enough for a counterexample for a non-Noetherian ring. I'll correct it. | |
| Jun 13, 2017 at 20:59 | comment | added | Count Dracula | It is not true that a flat module over a local ring is projective. Projective modules over local rings are free, but flat ones aren't... for example the rationals over the locazation of the integers at a prime. | |
