包含平方根非线性的 Schamel-Korteweg-de Vries (S-KdV) 方程对于研究等离子体和尘埃等离子体中的离子声波来说是一个非常有吸引力的模型。在这项工作中,我们采用 exp 函数方法获得了 S-KdV 方程的精确行波解。一般来说,精确的行波解将有助于非线性演化方程的理论和数值研究。这项工作强调了该方法在为不同物理问题提供独特解决方案方面的力量。
The Schamel-Korteweg-de Vries (S-KdV) equation containing a square root nonlinearity is a very attractive model for the study of ion-acoustic waves in plasma and dusty plasma. In this work, we obtain exact travelling wave solutions of the S-KdV equation by employing the exp function method. In general, the exact travelling wave solutions will be helpful in the theoretical and numerical study of the nonlinear evolution equations. The work emphasizes the power of the method in providing distinct solutions of different physical problems.
