This is an incomplete list for a variety of reasons. I did not include papers
that were published before the advent of serious electronic publishing, that is
TeX. Some older papers exist in troff form, but are not included. Then,
possibly, there were papers prepared electronically in that (not so distant)
past, but I have no record of those. Most of papers below are published, but
some are not. Some are so old that they show (for unclear reasons) from last to
first page. Moreover, these papers are reproduced as they are in my files, not
necessarily using the style files required by conferences, journals etc.
