Abstract

In this paper, we use the dynamical system method to investigate the wave solutions of the KdV-nKdV equation. We prove Wazwaz’s proposal that the KdV-nKdV equation has continuous periodic wave solutions and give their exact expressions by elliptic integral theory. We confirm that the KdV-nKdV equation has no classical solitary wave solution although it can be regarded as a fusion of the KdV equation with classical solitary wave and the nKdV equation. In addition, we obtain some novel traveling wave solutions of it including trapezoidal wave, inverted ‘N’ wave, and blow-up wave solutions.

kdv-nkdv方程的行波

本文用动力系统方法研究了KdV-nKdV方程的波动解。用椭圆积分理论证明了Wazwaz关于KdV-nKdV方程具有连续周期波解的建议，并给出了它们的精确表达式。我们证实了KdV-nKdV方程没有经典孤立波解，尽管它可以看作是KdV方程与经典孤立波和nKdV方程的融合。此外，我们还得到了它的一些新的行波解，包括梯形波解、倒“N”波解和爆破波解。
