For those who suffered my ill-zoomed browser presentation at the Fredericton Tensored Categories session earlier today -- as well as for those who had no opportunity to attend -- the set of HTML slides I had intended to sequence through is on the web beginning at the URL: | http://tlvp.net/~fej.math.wes/CMS-June2010/index0.htm . Be sure you start with your browser at its original default zoom setting -- if necessary, try resetting that with [Ctrl]-0 -- and that you are viewing things "full-screen" (often that's [F-11]). [For an abbreviated set of slides, start instead at | http://tlvp.net/~fej.math.wes/CMS-June2010/index.htm and click on each of the hot digits 1 through 10, seriatim, using your [Back] button to return to the index page each time.] Cheers, and apologies once again for the zoom-level setting fiasco, -- Fred [For admin and other information see: http://www.mta.ca/~cat-dist/ ]
