关于Ginzburg-Landau泛函极小元的唯一性

On the uniqueness of minimisers of Ginzburg-Landau functionals

Radu Ignat, Luc Nguyen, Valeriy Slastikov, Arghir Zarnescu

摘要:

在适当的凸性假设下,我们给出了$\mathbb{R}^n$值映射的Ginzburg-Landau泛函极小值的唯一性的充要条件,并给出了在固定方向上非负的$e\in \mathbb{S}^{n-1}$的$H^{1/2} \cap L^\infty$边界数据的唯一性.此外,我们表明,当极小是不唯一的,一组极小是从它的任何元素使用适当的正交变换的$\mathbb{R}^n$。我们还证明了调和映射的相应结果

英文摘要:

We provide necessary and sufficient conditions for the uniqueness of minimisers of the Ginzburg-Landau functional for $\mathbb{R}^n$-valued maps under a suitable convexity assumption on the potential and for $H^{1/2} \cap L^\infty$ boundary data that is non-negative in a fixed direction $e\in \mathbb{S}^{n-1}$. Furthermore, we show that, when minimisers are not unique, the set of minimisers is generated from any of its elements using appropriate orthogonal transformations of $\mathbb{R}^n$. We also prove corresponding results for harmonic maps
