BARRY SIMON
I.B.M. Professor of Mathematics and Theoretical Physics

Barry wins AMS Steele Prize for Lifetime Achievment!  AMS Announcement.  Caltech Press Release. OP-SF Net Announcement. AMS Page of All Winners.

                    NOTE: I will miss the AMS Prize ceremony on Jan 7, 2016, because the Bolyai Prize Ceremony was previously scheduled for Jan 6, 2016 in Budapest!

Barry's 70th birthday conference at Fields Institute (Toronto) and CRM (Montreal) -- August 22-September 1, 2016.  

In the second half of 2015, the AMS will publish Barry’s 5 Volume A Comprehensive Course in Analysis all at the same time.  Here is a preview.  Here is the facebook page.
