弹性流的Lojasiewicz-Simon不等式

The Lojasiewicz-Simon inequality for the elastic flow

Carlo Mantegazza, Marco Pozzetta

摘要:

定义$\mathbb{R}^n$中光滑浸入闭曲线的弹性能为长度与曲率的$L^2$ -范数之和,关于长度测度.我们证明了这种能量的$L^2$ -梯度流光滑地渐近收敛到一个临界点。我们的目的之一是目前的应用Lojasiewicz-Simon不等式,这是在证明的核心,在一个相当简洁和通用的方式。

英文摘要:

We define the elastic energy of smooth immersed closed curves in $\mathbb{R}^n$ as the sum of the length and the $L^2$-norm of the curvature, with respect to the length measure. We prove that the $L^2$-gradient flow of this energy smoothly converges asymptotically to a critical point. One of our aims was to the present the application of a Lojasiewicz-Simon inequality, which is at the core of the proof, in a quite concise and versatile way.
