Thanks for that. Aside from your homological program I was wondering if you knew stuff about Fitting ideals, which I've wanted to understand myself. Also, from the point of view of the geometry, we really need an article about Kähler differentials.

Hi Charles, I do know something about Fitting ideals and years ago I wrote up a longish thing on Kaehler differentials which I never finished and is now long gone. It would be good to do something on it but it will take some time.

The matricies in the example Koszul complex were denoted by psi and phi. I changed this to the more standard d_1 and d_2. Note that the complex has its differentials slightly in the wrong position, wiki doesn't seem to accept the \overset command.
