报告摘要：A revised Yau's Curvature Difference Flow is considered to deform one convex curve X0 to another one X. It is proved that this flow exists globally on time interval [0,+∞) and the evolving curve, preserving its convexity and bounded area A, converges to a fixed limiting curve X∞ (congruent to A/AX) as time tends to infinity, where A is the area bounded by the target curve X.
