The document discusses the seven Millennium Prize Problems in mathematics. These are seven problems stated by the Clay Mathematics Institute in 2000 that each carry a $1 million prize for a correct solution. Six problems remain unsolved. The problems include the P vs NP problem, Hodge conjecture, Riemann hypothesis, Yang-Mills existence and mass gap, Navier-Stokes existence and smoothness, and the Birch and Swinnerton-Dyer conjecture. The only solved problem was the Poincare conjecture, proven by Grigori Perelman in 2003.
