One of the greatest mathematicians of our time is Grigori Perelman. Perelman solved one of the most difficult problems in mathematics that has puzzled mathematicians for a hundred years, the Poincaré Conjecture.
The Poincaré Conjecture was posted by Henri Poincaré in 1904. It was one of the seven Millenium Prize Problems, the most difficult mathematics problems selected by the Clay Mathematics Institute. A correct solution to any of the unsolved problems can earn the author 1 million dollars. As of this writing, the remaining six problems are still unsolved. » Read more
On May 24, 2000, the Clay Mathematics Institute established seven Prize Problems. These problems are called the Millenium Prize Problems. A solution to each unsolved problem is worth $1 000 000 dollars. These problems are
- P versus NP
- Hodge conjecture
- Poincaré conjecture
- Riemann hypothesis
- Yang–Mills existence and mass gap
- Navier–Stokes existence and smoothness
- Birch and Swinnerton-Dyer conjecture
As of this writing (12 years later), six problems are still unsolved. The Poincare Conjecture was solved by Grigori Perelman in 2006. Dr. Perelman was awarded the Millenium Prize in 2010, but he declined the award.
