The papers on this page have never appeared in print, butin all other respects most of them are not any worse thanmy published ones. Some of them will eventually be rewrittenand publishedsomewhere; others will be deleted as soon as they get"out of date". They are of different quality and writtenin different style. I hope that 90% of them are understandable,but when reading them, you should never forget that I wrotethem for myself rather than for anyone else.
