FAQ About Grigori Perelman

What role did the Ricci flow play in Perelman's proof?
The Ricci flow was central to Perelman's proof of the Poincaré Conjecture. Introduced by Richard S. Hamilton, it is a process that deforms the metric of a manifold in a manner analogous to heat diffusion. Perelman utilized this concept to analyze and modify the geometric structure of 3-manifolds, eventually demonstrating how such structures evolve to reveal an underlying 3-sphere framework. This approach was crucial, providing new insights and techniques applicable within broader mathematical contexts.
