Stability analysis for the anisotropic curve shortening flow of planar networks

Michael Gößwein, Matteo Novaga, Paola Pozzi

AI总结:

该文研究三曲线平面网络的各向异性曲线缩短流,通过证明各向异性曲率能量满足Łojasiewicz-Simon梯度不等式,得出接近局部能量极小值的初始数据对应流全局存在且收敛于能量极小值的稳定性结论。

摘要:

本文研究三条曲线构成、端点固定且交汇于三重点的平面网络的各向异性曲线缩短流。我们证明各向异性曲率能量满足Łojasiewicz-Simon梯度不等式,并利用该结论推导流的稳定性结果。具体而言,我们的主定理表明,对于任意与(局部)能量极小值点$C^{2,α}$接近的初始数据,该流全局存在并收敛于一个可能不同的能量极小值点。

英文摘要:

In this article we study the anisotropic curve shortening flow for a planar network of three curves with fixed endpoints and which meet in a triple junction. We show that the anisotropic curvature energy fulfills a Lojasiewicz-Simon gradient inequality and use this knowledge to derive stability results for the flow. Precisely, in our main theorem we show that for any initial data, which are $C^{2,α}$-close to a (local) energy minimizer, the flow exists globally and converges to a possibly different energy minimum.
