摘要: We will present two reformulations for steady periodic water waves in two-layer flows. Then we present a variational formulation by showing that critical points of a natural energy functional are solutions to the governing equations. Provided that there are no stagnation points in the flow, we show that each streamline, including the free surface and the interface, is a real analytic curve if the height function has suitable regularity.
