在$\mathbb{R}^2$中构造Landau-Lifshitz-Gilbert方程部分正则解

The Construction of a Partially Regular Solution to the Landau-Lifshitz-Gilbert Equation in $\mathbb{R}^2$

Joy Ko

摘要:

我们建立了一个框架,以构造一个整体的解决方案,在有限能量空间的一般形式的Landau-Lifshitz-Gilbert方程的$\mathbb{R}^2$。我们的刻画产生了一个部分正则解,光滑远离2维局部有限Hausdorff测度集。这种构造依赖于通过离散化的近似,使用特殊的几何来表示其最高阶项是线性的等效系统,以及将基本解上的线性估计的机器从连续设置转换为离散设置。这种方法是相当普遍的,并适应更一般的几何形状,涉及目标是紧凑的光滑超曲面。

英文摘要:

We establish a framework to construct a global solution in the space of finite energy to a general form of the Landau-Lifshitz-Gilbert equation in $\mathbb{R}^2$. Our characterization yields a partially regular solution, smooth away from a 2-dimensional locally finite Hausdorff measure set. This construction relies on approximation by discretization, using the special geometry to express an equivalent system whose highest order terms are linear and the translation of the machinery of linear estimates on the fundamental solution from the continuous setting into the discrete setting. This method is quite general and accommodates more general geometries involving targets that are compact smooth hypersurfaces.
