I noticed lately that the principal entry page to my various web postings neglected to offer access to the slides I'd made for a talk I gave at CUNY Grad Center back in the fall of 2009. The slides were already there -- just no pointer to them. I've rectified that now -- the pointer (link-text "CUNY-2009") is at http://tlvp.net/~fej.math.wes/index.htm#CUNY-2009 . [You may require one or two applications of [Ctrl]-[Minus] to help avoid scroll bars screwing up the slides. Progress through them by hitting the little arrow in the URH blue zone.] Thanks; and sorry to trouble you with this. -- Fred [For admin and other information see: http://www.mta.ca/~cat-dist/ ]
