Jun 15, 2011 at 2:49 comment added Angelo To Nham: if you want to work with Cohen-Macaulay varieties, you'd better study local cohomology, which is a truly basic tool. "Translating into geometry" seems to me to be an unreasonable request.

Jun 15, 2011 at 0:44 comment added Nham Ngo Dear Karl, I really appreciate your considering on the second part. I have no ideas about local cohomology. I'll be more grateful if you can interpret the idea into geometry. Especially, I'm interested in when the intersection of 2 Cohen-Macaulay varieties is Cohen-Macaulay. Thanks!!!
