A note on the amplitude modulation of symmetric regularized long-wave equation with quartic nonlinearity
We study the amplitude modulation of a symmetric regularized long-wave equation with quartic nonlinearity through the use of the reductive perturbation method by introducing a new set of slow variables. The nonlinear ...
An application of multiple-time scale perturbation method to nonlinear ion-acoustic waves
(PHYSICAL SOC JAPAN, 2012-02)
In this work, by utilizing the multiple-time scale expansion method, we studied the propagation of weakly nonlinear waves in a collisionless cold plasma and obtained the governing evolution equations of various order terms ...
