The invariant subspace method and exact solutions for a nonlinear evolution equation
【摘要】 应用不变子空间方法构造了一个非线性演化方程的精确解,通过分别考虑其2阶和3阶不同的不变子空间,获得了3个具有分离变量形式的精确解.通过和已有的解比较,所得的解都是首次报道的新解.
【Abstract】 The invariant subspace method was applied to construct exact solutions of a nonlinear evolution equation,and three solutions in the form of separation of variables were successfully obtained with the help of different invariant subspaces.Compared with known solutions,these solutions were first reported new solutions.
