STUDYING A CLASS OF CURVE FLOWS ON THE SPHERE VIA CHORD-ARC ESTIMATES
摘要
Abstract
In this paper,we study the following curve shortening flow:Xt=k/KN.Using the spherical chord-arc estimate method,we obtain that any initially smooth embedded closed spherical curve evolving under this flow preserves the vanishing total geodesic curvature ∫xk,and eventually converges to a simple closed geodesic on the sphere.This provides a relatively concise proof for the extension of Gage's conjecture to the sphere.关键词
