Ricci Flow, a fundamental concept in differential geometry, was developed by Richard S. Hamilton to even out curvature in Riemannian manifolds. It's essential for understanding geometric and topological properties of spaces, and was key in proving the Poincaré Conjecture. This text delves into its mathematical dynamics, visualization in 2D geometries, and diverse variations, highlighting its significance in geometry and theoretical physics.
