Ben's preprints and papers

Here are my publications, grouped by rough category. I also have a page of unpublished notes which may be of some interest. All except my earliest few papers are available on the arxiv, where they are listed in reverse chronological order. In some cases the published version may differ slightly from the version linked here.
