研究了一类描述球上曲线流的五阶非线性色散偏微分方程的初值问题。该方程的一个典型例子出现在包含一维经典海森堡铁磁自旋模型的完全可积系统族中。本文在周期边界条件下建立了初值问题解的局部存在唯一性。证明是基于能量方法结合一种规范变换,以克服困难的导数损失。
The initial value problem for a fifth-order nonlinear dispersive partial differential equation describing the curve flow on the sphere is considered. A typical example of the equation arises in a hierarchy of completely integrable systems containing one-dimensional classical Heisenberg ferromagnetic spin model. This paper establishes the local existence and uniqueness of a solution to the initial value problem under the periodic boundary condition. The proof is based on the energy method combined with a kind of gauge transformation to overcome the difficulty of a loss of derivative.
