  The Story of the Million Dollar Poincaré Conjecture

Abstract:  In 2000, the Clay Mathematics Institute placed a bounty of one million dollars on each of seven unsolved problems in mathematics encompassing some of the most difficult issues with which mathematicians were grappling at the turn of the century.  In 2002 Grigory Perelman of St. Petersburg, Russia posted online a solution to the Poincaré Conjecture, one of these "Milennium Prize Problems".  Mathematicians have been on the edge of their seats ever since, torn between elation at the possibility of having found a solution and regret at the closure of one of mathematics' storied quests.  2006 is the first year the mathematics community has been able to confirm (after rigorous review) that Perelman's proof is valid.  In the meantime the story has turned in unexpected directions.  Perelman has shown little interest in the million dollar prize, and in August of 2006 he declined the Fields Medal, the highest honor in mathematics, which he was awarded in part for his proof of the Poincaré Conjecture.  Other people have meanwhile laid claim to some of the credit for the proof.  Disputes over who solved the Poincaré Conjecture, allegations of defamation, and lawsuits are rocking the mathematics community while Perelman is likely at home proving another theorem.  Come see why the Poincaré Conjecture has intrigued mathematicians for 100 years, what Perelman saw that no one else did, and hear about the cast of characters involved.



Biographical sketch: Katherine Crowley did her undergraduate work at St. Olaf College and her graduate work at Rice University.  Her mathematical interests lie at the intersection of topology, geometry, and combinatorics.  After finishing her Ph.D. she toured the country a bit, doing a postdoc at Columbia University for three years, and teaching at St. Olaf for one year, before settling into a position at Washington and Lee University just down the road from JMU.  She is quite fond of hiking, biking, and life in general in the Shenandoah Valley.
