备  注：Abstract：In this talk, I will introduce how to derive and justify fluid equations, such as acoustic syetem, compressible and incompressible Stokes system, incompressible Navier-Stokes equations and more general weakly compressible systems in various boundary conditions from the Boltzmann equations. We will focus on the justifications from DiPerna-Lions renormalized solutions of the Boltzmann equations. Furthermore, I will introduce the kinetic-fluid coupled boundary layers theory recently developed by myself and Masmoudi.
