Notes and Recreational Papers
William H. Press
These are unpublished works, including pedagogical and working notes on technical topics, but also including recreational papers on subjects that have attracted my interest. These notes may be cited as "W.H. Press (unpublished paper)", with the appropriate reference to this page. Hopefully, each is useful to at least someone.
