The Poincaré conjecture may now attract the first Millennium Prize to be awarded. In late 2002, Grigori Perelman of the Steklov Institute of Mathematics, Saint Petersburg was rumoured to have found a proof. He claimed to have proven a more general conjecture, Thurston's geometrization conjecture, carrying out a program outlined earlier by Richard Hamilton. In 2003, he posted a second preprint and gave a series of lectures in the United States. After several years of combined efforts of mathematicians from around the globe and intense reworking of Perelman's preprints, several teams of mathematicians have concluded Perelman's work is correct.
In June 2006, the Asian Journal of Mathematics published a paper by Cao Huaidong of Lehigh University in Pennsylvania and Zhu Xiping of Sun Yat-sen University in China, which has filled in the details of Perelman's work, thus "putting the finishing touches to the complete proof of the Poincaré Conjecture", according to the Fields medalist Shing-Tung Yau. http://english.people.com.cn/200606/04/eng20060604_270860.html http://www.intlpress.com/AJM/AJM-v10.php "O Binômio de Newton é tão belo como a Vênus de Milo.
