One day I will make this page look nice (the day after I finish tidying
my office). In the meantime, this will have to do.

Note: not all the PDF files of my published papers are
included here.
Those that are do not necessarily correspond to the final versions,
so should not be used for definitive reference. I still have paper offprints

....the HTML version of the paper on the journal webpage has a garbled
bibliography, presumably the work of some translation robot.
The (human) copy editor insisted (despite my protestations) on replacing
"fibre" with "fiber", and managed to misspell "après"  rather
less than one might hope from "Oxford" Journals and "International"
Mathematics Research Notices.
