Abstract:
The aim of this talk is to present a new evolution problem for convex
plane curves which is determined by both local (curvature $\kappa$ )
and global (area $A$) geometric quantities of the evolving curve. This
flow will decrease both the perimeter of the evolving curve and the area
it bounds and make the evolving curve more and more circular during the
evolution process. And finally, as $t$ goes to infinity, the limiting curve
will be a circle in the $C^{\infty}$ metric.
