Internal waves in a 2D subcritical channel

Abstract

We study scattering and evolution aspects of linear internal waves in a two dimensional channel with subcritical bottom topography. We define the scattering matrix for the stationary problem and use it to show a limiting absorption principle for the internal wave operator. As a result of the limiting absorption principle, we show the leading profile of the internal wave in the long time evolution is a standing wave whose spatial component is outgoing.
