KdV equation in the quarter--plane: evolution of the Weyl functions and unbounded solutions
摘要:
在右上角四分之一平面上考虑了具有负色散项的矩阵KdV方程。导出了相应的辅助线性系的Weyl函数的演化规律。利用Weyl函数的低能渐近性,得到了几类初边值问题解的无界性。
英文摘要:
The matrix KdV equation with a negative dispersion term is considered in the right upper quarter--plane. The evolution law is derived for the Weyl function of a corresponding auxiliary linear system. Using the low energy asymptotics of the Weyl functions, the unboundedness of solutions is obtained for some classes of the initial--boundary conditions.
