Dirk Laurie's research

The PDF, DVI, PS and LJ files below are not copies of actual electronic publications and must be considered to have the status of preprints. The BibTeX information supplied was up-to-date at the time the PDF file was uploaded, but may be obsolete by now. I have included some items that have not been, and may never be, published.
