Publications and Preprints

All of my papers and preprints are stored on arXiv.org. Each paper below is linked to the user-friendly UC Davis Front to the archive. The papers here 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).
