一类凸曲线流在Ros等周不等式中的应用
|
Abstract:
通过平面中一类面积非减的凸曲线流,曲线在发展过程中保持凸性不变,具有全局存在性,且当时间趋于无穷大时,曲线在C0范数下收敛到圆。我们建立该曲线流的单调公式,给出了平面上Ros等周不等式新的证明。
By convex curve flow with non-decreasing area in the plane, the curve remains convex and exists globally, and the evolving curve converges to a circle as the time goes to infinity. A new proof of the plane Rose isoperimetric inequalities is given by establishing the monotone formulas along the curve flow.
