本文考虑了在广义Oseen-Frank能量下从$\R^2 $到单位球$S^2$的铁磁自旋链的Landau-Lifshitz方程.对于大能量数据,我们得到了整体弱解的存在唯一性,而且奇异点的个数是有限的。
In this paper, we consider the Landau-Lifshitz equation of the ferromagnetic spin chain from $\R^2$ to the unit sphere $S^2$ under the general Oseen-Frank energy. We obtain global existence and uniqueness of weak solutions for large energy data; moreover, the number of singular points is finite.
