内容摘要：

In this talk, we shall study the well-posedness of the initial boundary value problem for the two-dimensional compressible ideal flow with the impermeable boundary condition in domains with corners, and the small viscosity limit for the two-dimensional incompressible viscous flow with the Navier boundary condition in a quarter space, in which it is observed the boundary layer near each edge satisfies the linearized Prandtl equations and the corner layer produced by the interaction of two boundary layers satisfies the nonlinear Navier-Stokes type equations. It is based on joint work with Wen Guo.
