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.
