x,t平面上与零曲率有关的非线性Schrodinger(NLS)和Korteweg de Vries(KdV)方程的孤子解

摘要:

非线性NLS和KdV方程的孤子解与描述辅助函数Psi在x,t平面上的零曲率运动的矩阵M和H之间的相容性条件有关。函数u的非线性方程由相容性方程得到,其中M和H的矩阵元素仅包括u及其导数的函数。通过求解Psi的运动方程,得到了u的孤子解.分别用二维和一维波函数Psi对NLS和KdV孤子进行了显式计算。

英文摘要:

Soliton solutions of non-linear NLS and KdV equations are related to compatibility condition between matrices M and H describing the movement of an auxilary function Psi in the x,t plane with a zero curvature condition. Non-linear equation for a function u is obtained by the compatibility equation where the matrix elements of M and H include only functions of u and its derivatives. By solving the equations of motion for Psi a soliton solution for u is obtained. Explicit calculations are made with two-dimensional and one-dimensional wave functions Psi for the NLS and KdV solitons, correspondingly.
