Here are
several papers that I am making available online. These are
not necessarily the final versions, just the latest .ps file that I have handy. The journal
version will often have many errors corrected (and some still
uncorrected). The copyright for each journal paper belongs to
the publisher of that journal. Last updated Apr 2015.
