FAQ About Grigori Perelman
How did Grigori Perelman prove the Poincaré conjecture?
Grigori Perelman built on the earlier work of Richard S. Hamilton, using a technique known as Ricci flow. He introduced new ideas and techniques to handle singularities that arise in the Ricci flow, ultimately providing a proof of the Poincaré conjecture over several papers published online from 2002 to 2003.
