摘要
对于不具有拉格朗日函数的(2+1)维BBM-Burgers方程,通过引进其Fréchet导数共轭方程的方法得到扩充方程组.利用Noether法研究了该扩充方程组的守恒律,给出了(2+1)维BBM-Burgers方程的扩充守恒律及守恒向量.
The BBM-Burgers equation can not be matched with the exact and proper Lagrangian function, so the theory of self-adjoint differential operators can be used to obtain the expanded system of equations. Then, the expanded conservation laws of this expanded system of equations is obtained by means of Noether theorem.
