摘要
运用李群对称方法解决Bretherton方程问题,得到方程的对称约化和群不变解,比如幂级数解,最后得出该问题的守恒率.
By applying the direct symmetry method to Bretherton equation, the symmetry reductions, group invariant solutions of this equation were obtained, such as, the power series solution. At last, the conservation laws of this equation were given.
