nonlocal curvature flows of closed curves in the plane

abstract:

we first talk about gage's area-preserving flow (gapf) for simple, smooth and star-shaped curves. it is shown that gapf drives a centrosymmetric initial curve into a circle as time tends to infinity. then we generalize gapf to deform one convex curve to another. this work gives a partial answer to yau's problem on realizing whitney-graustein theorem via curvature flows.
