Unsolved Mathematical Problems

problems

Several prizes are waiting to be awarded for outstanding mathematical achievement. The most prestigious mathematical award is the Fields medal. Other awards are the Wolf Prize from the Wolf Foundation of Israel, the Leroy P. Steele Prize of the American Mathematical Society, the Bôcher Prize, Cole Prizes in algebra and number theory, and the Delbert Ray Fulkerson Prize, all presented by the American Mathematical Society.

institueIn 2000, The Clay Mathematics Institute of Cambridge, Massachusetts (CMI) named seven “Millennium Prize Problems,” selected by focusing on important classic questions in mathematics that have resisted solution over the years. A $7 million prize fund was established for the solution to these problems, with $1 million allocated to each. The problems are:

 

 

1. Riemann hypothesis
2. Poincaré conjecture (the correct solution was confirmed in 2006, the prize was turned down)
3. Hodge conjecture
4. Swinnerton-Dyer conjecture
5. solution of the Navier-Stokes equations
6. formulation of Yang-Mills theory
7. determination of whether NP-problems are actually P-problems.
