  • On the 24th of May 2000, seven complex mathematical problems were officially designated as Millennium Problems during a ceremony at the Collège de France in Paris. John Tate and Michael Atiyah announced these challenges to an audience gathered in the amphithéâtre Marguerite de Navarre. The Clay Mathematics Institute pledged one million US dollars for the first correct solution to each problem. This event marked the formal selection of the Birch and Swinnerton-Dyer conjecture, Hodge conjecture, Navier, Stokes existence and smoothness, P versus NP problem, Riemann hypothesis, Yang, Mills existence and mass gap, and the Poincaré conjecture. Unlike previous efforts like David Hilbert's twenty-three problems from 1900, these selected issues were already renowned among professional mathematicians. Many experts were actively working towards their resolution before this official announcement.

  • Grigori Perelman released his proof of the Poincaré conjecture in 2002 and 2013 after beginning work on it in the 1990s. He declined the Clay Institute's monetary prize awarded on the 18th of March 2010 because it was not also offered to Richard S. Hamilton. Hamilton had developed a program over the preceding twenty years that Perelman completed with his own contributions. Their work revolved around Hamilton's Ricci flow, which is a complicated system of partial differential equations defined in the field of Riemannian geometry. Perelman also refused the Fields Medal in 2006 for his contributions to the theory of Ricci flow. The media widely covered his refusal of both awards as he stated Hamilton's contribution was no less than his own.

  • Six Millennium Prize Problems remain unsolved despite numerous attempts by both amateur and professional mathematicians. The Birch and Swinnerton-Dyer conjecture deals with elliptic curves over rational numbers and whether they have finite or infinite solutions. Andrew Wiles gave the official statement of this problem while Pierre Deligne provided the modern statement for the Hodge conjecture. Charles Fefferman presented the Navier, Stokes existence and smoothness problem regarding fluid motion equations. Stephen Cook formulated the P versus NP question about verifying solutions quickly versus finding them quickly. Enrico Bombieri explained the Riemann hypothesis concerning nontrivial zeros of the zeta function. Arthur Jaffe and Edward Witten established the requirements for quantum Yang-Mills theory existence and mass gap.

  • Anatoly Vershik characterized the monetary prize as show business representing the worst manifestations of present-day mass culture. He believed there were more meaningful ways to invest in public appreciation of mathematics than offering cash rewards. Shing-Tung Yau echoed these criticisms by objecting to a foundation taking actions to appropriate fundamental mathematical questions. Yau felt it inappropriate to attach its name to such deep theoretical inquiries. Conversely, Andrew Wiles hoped that the one million dollar prize would popularize the selected problems among general audiences. Alain Connes also supported the initiative hoping publicity would combat the wrong idea that mathematics would be overtaken by computers. The Clay Institute's direct funding of research conferences and young researchers received praise from critics like Vershik despite their objections to the prize structure itself.

  • The Clay Mathematics Institute drew inspiration from a set of twenty-three problems organized by mathematician David Hilbert in 1900. These earlier challenges were highly influential in driving the progress of mathematics throughout the twentieth century. The seven Millennium Problems span fields including algebraic geometry arithmetic geometry geometric topology mathematical physics number theory partial differential equations and theoretical computer science. Unlike Hilbert's problems which were new at the time, the modern selection included issues already renowned among professional mathematicians. Bernhard Riemann originally posed his hypothesis in 1859 making it over a century old when included in the 2000 list. Henri Poincaré had asked about three-dimensional shapes back in 1904 establishing another century-long tradition of inquiry before the Clay Institute formalized these specific challenges.

Common questions

When were the Millennium Prize Problems officially designated?

The seven complex mathematical problems were officially designated as Millennium Problems on the 24th of May 2000 during a ceremony at the Collège de France in Paris. John Tate and Michael Atiyah announced these challenges to an audience gathered in the amphithéâtre Marguerite de Navarre.

Who solved the Poincaré conjecture and when did they release their proof?

Grigori Perelman released his proof of the Poincaré conjecture in 2002 and 2013 after beginning work on it in the 1990s. He declined the Clay Institute's monetary prize awarded on the 18th of March 2010 because it was not also offered to Richard S. Hamilton.

Which six Millennium Prize Problems remain unsolved today?

Six Millennium Prize Problems remain unsolved despite numerous attempts by both amateur and professional mathematicians. These include the Birch and Swinnerton-Dyer conjecture, Hodge conjecture, Navier, Stokes existence and smoothness, P versus NP problem, Riemann hypothesis, and Yang, Mills existence and mass gap.

What is the monetary value of the Clay Mathematics Institute prize for each solution?

The Clay Mathematics Institute pledged one million US dollars for the first correct solution to each problem. This event marked the formal selection of seven specific mathematical challenges including the Riemann hypothesis and the Poincaré conjecture.

Why did Grigori Perelman refuse the Fields Medal and the Clay Institute prize?

Perelman refused the Fields Medal in 2006 and the monetary prize awarded on the 18th of March 2010 because he believed Richard S. Hamilton deserved equal recognition. Their work revolved around Hamilton's Ricci flow which is a complicated system of partial differential equations defined in the field of Riemannian geometry.
