I watched every possible documentary about Perelman and noticed that he never interviewed and he doesn’t want to be bothered about the price, eventually I came to conclusion that it was only the math that matters to him. Think about it, this man worked and put his mind for almost a decade to come with completely new thing and after he reviled it to the world and it was fascinating for all mathematicians, a person might feel an emptiness that he will never repeat it again, and then others coming to him and suggest a reword and he is completely in a different place in his life, he brought a huge thing that there is no reword that can fill this emptiness. This is how I saw it after watching the path he went thru. Hope I’m not to mystical 😅

I believe perlman rejected the prize because the guy (Richard Hamilton?) who came up with Richie flow was not going to be honored and recognized. Perlman refused the prize because he felt part of the work wasn't his, and as a result, he does not have a right to claim the reward for himself. I guess he could have also given part of the cash to the guy, but such prized are more than about $. Perlman is a man who lives by principles he does not violate, the same principles, which helped him solve this riddle in the frist place.

If I’m not mistaken, Perelman also declined the Millennium Prize and its $1M USD award besides just the Fields medal. He explained it as unfair to Hamilton (and others?) whose Ricci Flow analytical achievements were just as deserving of any fame & fortune.

@JoshBBB 3 года назад

From Wikipedia, for what it’s worth… “The Poincaré conjecture, before being proved, was one of the most important open questions in topology. In 2000, it was named one of the seven Millennium Prize Problems, for which the Clay Mathematics Institute offered a $1 million prize for the first correct solution. Perelman's work survived review and was confirmed in 2006, leading to his being offered a Fields Medal, which he declined. Perelman was awarded the Millennium Prize on March 18, 2010.[6] On July 1, 2010, he turned down the prize, saying that he believed his contribution in proving the Poincaré conjecture was no greater than Hamilton's.[7][8] As of 2021, the Poincaré conjecture is the only solved Millennium problem.”

@bmclaughlin01 3 года назад

Grigori’s proof was about 100 pages, each page had teams of Mathematicians to assess and check every detail, they found this to be extremely difficult and Yau’s students were involved in fleshing out the proofs, Perelman just didn’t go into every detail but was annoyed because Yau starting playing Politics claiming his students also solved P. The real genius of his proof was to use a geometrical argument instead of a Topological one. It was always thought this could only be done using Topology and with Thurston running through every unsolved proof in Topology, it was expected he would solve Poincare easily but it proved impossible via Topology.

8:30 Maybe you have met assholes, but has any of them taken your work, rephrase it a little and try to pass it on as theirs? And not just that, they get caught, try to say they are "bettering your work" and noone cares? Worse than "noone cares", they stay the Dean of Mathematics in Harvard and face no repercussions. Of course Perelman is is a non-typical character, but this whole ordeal would be enough for anyone to be disgusted with their community.

Perelman declined the prize because the foundations of his proof were based on Hamiltons work, therefore its sometimes called Hamilton-Perelman theory of Ricci flow by other scientists too. There is no Perelman without Hamilton

Частенько слышу от математиков в России, что деньги не важны, а важна математика. Можно процитировать Саватеева, что математику нет смысла гнаться за деньгами, так как если он хороший математик он всегда сможет их заработать. Я не уверен, что это была мотивация Перельмана, но определенные умонастроения такие витают. П.С. когда я работал конструктором в Роскосмосе, многие конструктора тоже выражали аналогичные умонастроения ЛОЛ. Но Аэрокосмическая отрасль не обладает такой универсальностью как математика, поэтому тут я с ними не мог согласится

A Russian Jew came to the USA and was disillusioned. In his paper, Finite extinction time for the solutions to the Ricci flow on certain three-manifolds Perlman states, "whether the solution becomes extinct in finite time for every initial metric on a manifold of this type. In this note we prove that this is indeed the case." He wanted Hamilton to get equal credit for his contributing work. He did not want to be put on display as a lap dog of the Clay Institute. My own thinking, world population becomes extinct in every case, except for those rare, inconvenient growths toward infinity in nearly zero time. Perlman chose to live in poverty with his mother in Russia. How does this make sense otherwise?
