One person reported trouble viewing my pdf file. If you
aren't able to view it, alternatively try getting the TeX
source file from
http://www.unk.edu/acad/math/people/willisb/home.html
To TeX my file, you'll also need to grab the battex.sty file
(also on my page).
(I successfully viewed the file from several machines; I don't know
the cause of the problem. I used the mathptm package. Is that the
cause?)
