Abstract:
A pseudo-spectral collocation method for a class of equations describing
resonant long-short wave interaction is studied. Semi-discrete and fully
discrete Fourier pseudo-spectral collocation schemes are given. In fully
discrete case we establish a three-level explicit scheme which is convenient and
saves time in real computation. We use energy estimation methods to obtain error
estimates for the approximate solutions.
Keywords:
Long-short wave interaction, pseudo-spectral collocation method, energy
estimation.
