| Jun 14, 2011 at 15:04 | comment | added | David White | @ehsanmo Rather than consider all ideals, I'd recommend simply using the equivalent definition of CM for local rings: A local ring is CM iff Krull dim(R) = depth(R) | |
| Jun 14, 2011 at 9:21 | comment | added | Ehsan M. Kermani | How do you deal with the equation $grade(I)=ht(I)$ for any ideal $I$ of $T$? | |
