| Nov 24, 2010 at 7:39 | comment | added | Fred Rohrer | A ring with ITI with respect to every ideal is not necessarily Noetherian. Indeed, a ring with the property that every proper ideal is nilpotent has ITI with respect to every ideal, hence it suffices to exhibit a non-Noetherian local ring with nilpotent maximal ideal. This we do by taking the polynomial algebra in countably many indeterminates over a field modulo the ideal generated by all products of two indeterminates. | |
