Aurelio

Dear Colleagues, We are so very sad that Aurelio is so unexpectedly gone. We will sorely miss his unique contributions to our community. It seems only yesterday (but actually it is 40 years) since he, in Perugia, started to teach me his unique Italian with the same enthusiasm that he applied to learning category theory. I never ceased to admire his quick grasp of mathematics, and his clear perception of situations and characters. My life (like the lives of many of us) was enriched by his commentaries both wry and profound, yet full of humor and kindness and warmth. As all the friends, I am deeply distressed at saying goodbye to Aurelio. Bill [For admin and other information see: http://www.mta.ca/~cat-dist/ ]
