[...] It solves an outstanding, century-old, problem.In May 2006, a committee of nine mathematicians voted to award Perelman a He had previously rejected a prestigious prize from the The Clay Institute subsequently used Perelman's prize money to fund the "Poincaré Chair", a temporary position for young promising mathematicians at the Paris Perelman quit his job at the Steklov Institute in December 2005.This, combined with the possibility of being awarded a Fields medal, led him to quit professional mathematics. Fellow countryman and mathematician In 2014, Russian media reported that Perelman was working in the field of Perelman has avoided journalists and other members of the media. In 1994, Perelman gave a short and elegant proof of the conjecture by establishing that in the general case Three notable papers of Perelman's from 1994 to 1997 deal with the construction of various interesting Riemannian manifolds with positive The Poincaré conjecture, proposed by French mathematician In November 2002, Perelman posted the first of three However, it was widely expected that the process would be impeded by developing "singularities."
Our editors will review what you’ve submitted and determine whether to revise the article.In the 1980s Thurston won a Fields Medal for his efforts to extend the geometric classification of two-dimensional
Two weeks later, Perelman summed up the conversation as follows: "He proposed to me three alternatives: accept … The Millennium problem is a award of 1 million dollars for solving any one of the 7 most important math problems, proposed by the Clay Math Institute.
About this I have no doubts [...] The thing is, there are very few experts in the area of Ricci flow, and I have not yet met anyone who claims to have a complete understanding of the last, most difficult part of Perelman's proof [...] As far as I'm aware, no one has taken some of the techniques Perelman introduced toward the end of his paper and successfully used them to solve any other significant problem.
Based on it, we shall give the first written account of a complete proof of the Poincaré conjecture and the geometrization conjecture of Thurston. He was the first mathematician ever to decline the Fields Medal. [...] In this paper, we shall give complete and detailed proofs [...] especially of Perelman's work in his second paper in which many key ideas of the proofs are sketched or outlined but complete details of the proofs are often missing. With this understanding, he was able to construct a modification of the standard Ricci flow, called Perelman showed that any singularity that develops in a finite time is essentially a "pinching" along certain spheres corresponding to the The contents of the three papers are summarized below: Topology is the mathematical study of shapes and spaces, and the will to define these precisely. Grigori Perelman, a Russian mathematician, solved one of the world's most complicated math problems several years ago. In the 1990s, Hamilton made progress on understanding the possible types of singularities which may occur, but was unable to provide a comprehensive description. Grigori Perelman, (born 1966, U.S.S.R.), Russian mathematician who was awarded—and declined—the Fields Medal in 2006 for his work on the Poincaré conjecture and Fields medalist William Thurston’s geometrization conjecture.

Categories The latest revision to their article was in 2013. I am convinced, as I've said many times before, that Perelman did brilliant work regarding the formation and structure of singularities in three-dimensional spaces—work that was indeed worthy of the Fields Medal he was awarded.
Millennium Problems: Title text: The hard part about opening a hole in the proof of the Poincaré conjecture is that Grigori Perelman will come out of retirement to try to fix it by drawing a loop around the hole and contracting it to a point.

The use of the word "application" in their title "A Complete Proof of the Poincaré and Geometrization Conjectures - Application of the Hamilton-Perelman Theory of Ricci Flow" and the phrase "This proof should be considered as the crowning achievement of the Hamilton-Perelman theory of Ricci flow" in the abstract were particularly singled out for criticism. Either to make some ugly thing or, if I didn't do this kind of thing, to be treated as a pet. When asked about the issue, Perelman said that Cao and Zhu had not contributed anything original, and had simply reworked his proof because they "did not quite understand the argument".As of 2020, there remain some mathematicians who are doubtful that the Poincaré and geometrization conjectures have been proven, although it is universally acknowledged that Perelman made tremendous strides in the theory of Although it may be heresy for me to say this, I am not certain that the proof is totally nailed down.
