Fluids interface problems appear in many important physical situations such as water waves, shape of gaseous stars, and gas flows though porous media. They are modeled by free boundary problems of Euler and Navier-Stokes equations. In this course, we will cover some basic theory in these topics with emphasize on the a priori estimates which lead to the well-posedness and behaviors of solutions.





Basic theory of PDE and Sobolev spaces.
