From the AMS website:
AMS President David Eisenbud organized an AMS Special Session, Current Events in Mathematics (1,617 KB pdf of the talks) at the Joint Mathematics Meetings, Friday, January 9. The well-attended session featured The Interior-Point Revolution in Optimization: History, Recent Developments and Lasting Consequences, presented by Margaret Wright; What Is Motivic Integration?, by Thomas C. Hales; It Is Easy to Determine Whether or Not a Given Integer is Prime, by Andrew Granville; and Perelman's Recent Work on the Classification of 3-Manifolds, by John W. Morgan.
The PDF file linked above is interesting, but a bit of a mess. The pages of the
four seperate article wind up being mixed up in a peculiar way. Too bad, as the speakers at the session worked to provide their contributions in electronic form
in a timely way.
