Preprints since 1995 - Douglas B. West

For additional information: my home page, list of abstracts (ps pdf), and publication list (ps pdf - includes citations for earlier papers in obsolete formats not easily convertible to postscript or pdf).

Note: Since pdf(la)tex does not support the tex specials produced by gpic, pdf versions of some papers with figures have been converted from postscript by ps2pdf. This produces lower font quality, so for these papers the ps versions will be preferable for screen viewing. This also holds for older papers (especially before 1999) written in groff or with tex macros that have changed.
