摘要
利用Noether法构造了KP方程新的守恒律,在KP方程允许的拉格朗日函数的情况下,利用Noether法研究了该方程的守恒律,给出了KP方程的Noether对称算子以及新的守恒向量和守恒律的分类结果.
In this paper,in terms of Noether approach,KP equation associated with Lagrange function is studied and its conservation laws are constructed.Then classification results of Noether-type symmetry,new conservation vectors and new conservation laws of the KP equation are obtained.
