摘要

在本文中，我们考虑了闭凸平面曲线的一种保面积流，它会在演化过程中减少演化曲线的长度，使演化曲线变得越来越圆。随着时间的推移，演化曲线的最终形状将是一个圆圈（t\rightarrow+\infty\）。

On a non-local area-preserving curvature flow in the plane

In this paper, we consider a kind of area-preserving flow for closed convex planar curves which will decrease the length of the evolving curve and make the evolving curve more and more circular during the evolution process. And the final shape of the evolving curve will be a circle as time \(t\rightarrow +\infty \).

期刊介绍： The first issue of the "Abhandlungen aus dem Mathematischen Seminar der Universität Hamburg" was published in the year 1921. This international mathematical journal has since then provided a forum for significant research contributions. The journal covers all central areas of pure mathematics, such as algebra, complex analysis and geometry, differential geometry and global analysis, graph theory and discrete mathematics, Lie theory, number theory, and algebraic topology.
