Mark Kleiman ask what the status is on the possible proof of the Poincare conjecture by Russian mathematician Grigory Perelman. The above Science News link (via Kleiman) is a great understandable background article on the conjecture, its history, and Perelman's work. The short answer is that the proof is still neither confirmed nor denied. The vetting continues.
Perelman's work appeared as a series of three papers which were made publicly available as preprints in November 2002, March 2003, and July 2003 respectively. None of them has been officially published yet, and only the first seems to have been extensively reviewed. For those interested Bruce Kleiner and John Lott (no not that John Lott) maintain a website for notes and commentary on Perelman's papers. Especially helpful for the more mathematically inclined is Misha Kapovich's notes of a talk he gave on the subject last September.
does anyone find it obvious that there is no flow if there is a high enough tempreture? Pearlman is mad. he might be brillian though.
