报告摘要： In this talk, we will discuss the local well-posedness of smooth solutions to the free boundary problem for relativistic and nonrelativistic compressible fluids in vacuum. This includes the relativistic Euler equations, as well as the classical and time-dependent compressible Euler equations with damping. We will also present key ideas for establishing the well-posedness of global smooth solutions under small perturbations around certain affine solutions.
