$S^1$-调和映射的变分方法及其应用

A variational approach to $S^1$-harmonic maps and applications

Filippo Gaia, Tristan Rivière

AI总结:

该研究提出带边或不带边曲面到$S^1$映射的Dirichlet拉格朗日量重整化程序,其有限能量临界点为带孤立奇点的$S^1$-调和映射,并给出该方案在两类几何问题中的应用。

摘要:

我们针对从带边或不带边曲面到$S^1$的映射,提出了一种Dirichlet拉格朗日量的重整化程序,其有限能量临界点就是带孤立奇点的$S^1$-调和映射。我们在两种不同框架下给出了该重整化方案的若干应用。第一个应用涉及Kähler-Einstein曲面中拉格朗日奇异浸入的Willmore能量重整化,第二个应用则针对欧几里得空间中曲面浸入的标架能量展开研究。

英文摘要:

We present a renormalization procedure of the Dirichlet Lagrangian for maps from surfaces with or without boundary into $S^1$ and whose finite energy critical points are the $S^1-$harmonic maps with isolated singularities. We give some applications of this renormalization scheme in two different frameworks. The first application has to do with the renormalization of the Willmore energy for Lagrangian singular immersions into Kähler-Einstein Surfaces while the second application is dealing with frame energies for surfaces immersions into Euclidian spaces.
