我们在场非线性的部分微分方程的特殊有条件的类似减小解决方案的一个方法。作为它的申请的具体例子,我们把这个方法用于(2+1 ) 维的修改 Broer-Kaup 方程和可变系数 KdV-mKdVequation,它有广泛的物理背景,并且获得丰富的准确答案源于一些减小方程。
We present a method of special conditional similarity reduction solutions for nonlinear partial differential equations, As concrete examples of its application, we apply this method to the (2+1)-dimensional modified Broer- Kaup equations and the variable coefficient KdV-mKdV equation, which have extensive physics backgrounds, and obtain abundant exact solutions derived from some reduction equations.
