报告题目 Numerical simulation of the generalized Zakharov system
Abstract:
In this talk, we propose a time-splitting spectral method
for the generalized Zakharov system. This method is spectrally accurate
in space, second order in time, and unconditionally stable.
The unconditional stability of the method offers greater
numerical efficiency than those given before, especially in the
subsonic regime.
Our numerical experiments confirm the accuracy and stability. Using this new method we study
the collision behavior of two solitons, in the subsonic region
as well as the transsonic region.
