The Russian mathematician, Grigori Perelman, rejected the $1 million prize because he believed that his proof of the Poincaré Conjecture was a contribution to the mathematical community and not something to be rewarded with money.
The Poincaré Conjecture is a famous and long-standing mathematical problem that was first proposed by Henri Poincaré in 1904. It deals with the shape and topology of three-dimensional spaces and has important implications in various fields of mathematics and physics.
No, Grigori Perelman never publicly explained his decision to reject the prize. He has been known to be a recluse and has avoided media attention since his work on the Poincaré Conjecture gained recognition.
No, Grigori Perelman's proof of the Poincaré Conjecture is the only one that has been accepted by the mathematical community. Although there have been other attempts to solve it, none have been accepted as complete and correct.
No, the $1 million prize for solving the Poincaré Conjecture was never given to anyone else. After Grigori Perelman rejected it, the Clay Mathematics Institute, who had offered the prize, decided not to award it to anyone else.
