In mathematics, the Poincaré conjecture is a theorem about the characterization of the 3-sphere Several teams of mathematicians verified that Perelman’s proof was correct. The Poincaré conjecture, before . The actual solution was not found until Grigori Perelman published his papers. In late and Perelman. Grigori Perelman was attributed a Fields Medal for «his history of the conjecture and the mathematical path that led to Perelman’s proof is. Perelman became infamous for not only declining the Fields medal, and the Millenium prize, but also denouncing the mathematical community in general for .

That is why I had to quit. The authors also removed the phrase “crowning achievement” from the abstract.

Retrieved August 15, He had previously rejected a prestigious prize from the European Mathematical Society. Archived from the original on January 17, Grigoriy Perelman of St. Everybody understood that if the proof is correct, then no other recognition is needed.

Such numbers are called eigenvalues of that operation. Perelman’s work survived review and was confirmed inleading to his being offered a Fields Medalwhich he declined.

Randerson, James August 16, Other people do worse. Archived from the original on July 21, Archived from the original on July 15, Weisstein, Eric April 15, Retrieved May 15, Archived from the original on September 17, The Ggrigori paper claimed: Nanocircuits or Molecular circuit Two weeks later, Perelman summed up the conversation as follows: In dimension three, the conjecture had an uncertain reputation grigoro the geometrization conjecture put it into a framework governing all 3-manifolds.

Of course, there are many mathematicians who are more or less honest.

October Learn how and when to remove this template message. According to William Thurston this normal form must take one of a small number of possibilities, each having a different kind of geometry, called Thurston model geometries.

The New York Times. Hamilton as a way to deform manifolds.

The New York Review of Books. Experts in the field were often reluctant to announce proofs, and tended to view any such announcement with skepticism.

Archived from the original on July 16, By studying the limit of the manifold for large time, Perelman proved Thurston’s geometrization conjecture for any fundamental group: Retrieved August 20, Similarly, the Ricci flow describes the behavior of a tensorial quantitythe Ricci curvature tensor.

This page was last edited on 1 Decemberat Archived from the original on March 19, He wanted to cut the manifold at the singularities and paste in caps, and then run the Ricci flow again, so he needed to understand the singularities and show that certain kinds of singularities do not occur. The article implies that Perelman refers particularly to perwlman efforts of Fields medalist Shing-Tung Yau to downplay Perelman’s role in the proof and play up the work of Cao and Zhu.

Archived from prood original on April 19, Asian Journal of Mathematics. Archived from the original on March 30, Completing the proof, Perelman takes any compact, simply connected, three-dimensional manifold without boundary and starts to run the Ricci flow. He needed to understand the singularities.

Now, when I become a very conspicuous person, I cannot stay a pet and say nothing.
