For each paper below, you can either download the PDF version directly from the link provided, or click on the title to go to that paper’s own little page, which has the abstract, MR reference information, link to the journal, and some notes about the paper. Most of these are also available from the arXiv.

I have a separate page for my book, Cohen-Macaulay Representations, with Roger Wiegand, as well as one for the book 24 Hours Of Local Cohomology by seven authors.

Also there’s this article for the MSRI newsletter about non-commutative resolutions, which I don’t know where to put.
