What is curve shortening flow?
—Curve shortening flow deforms paths on surfaces based on their curvature, moving each point orthogonal to the tangent line and proportional to the curvature.
What is mean curvature flow?
—Mean curvature flow deals with 3D surfaces in 4D space, moving each point orthogonal to its tangent plane at a rate determined by the average curvature.
What are singularities in Ricci flow?
—Singularities are points where curvature becomes infinite, causing the flow to stop. Mathematicians study them by performing surgeries to isolate and analyze their impact.
What are the wide applications of Ricci flow?
—Ricci flow has applications in geometry, topology, physics, and computer science. It helps analyze and understand the structure and properties of various objects and spaces.
