Publications and Preprints
All of my papers and preprints are stored on arXiv.org, and the papers there are
the definitive versions. They are identical in content to the
published versions except where the journal introduced errors
(e.g. the hilarious references to "Inventory Mathematics" in the
published version of paper 2).
