FAQ About Grigori Perelman
What is the Poincaré conjecture?
The Poincaré conjecture is a fundamental question in topology that was posed by Henri Poincaré in 1904. It suggests that every simply connected, closed 3-manifold is homeomorphic to the 3-sphere. This conjecture remained unsolved for nearly a century until Grigori Perelman provided a proof in the early 2000s.
