摘要
利用近似Noether-type对称算子构造了具有扰动项的(2+1)维Boussinesq方程的近似守恒向量和近似守恒律,在(2+1)维Boussinesq方程允许的拉格朗日函数的情况下,利用近似Noether法研究了该方程的守恒律,给出了(2+1)维扰动Boussinesq方程的近似Noether对称算子、近似守恒向量以及近似守恒律.
The method of constructing approximate conserved vectors and conserved laws for perturbed （2 ＋1）-dimensional Boussinesq equation are concretely described. In terms of the partial Lagrangian ap- proach, the conserved laws are constructed by using approximate Noether method, then the approximate Noether-type symmetry operators and approximate conserved laws are obtained.
