报告内容简介：
In the lecture series I will survey corner singularity and regularity results for the boundary value problems for the Poisson equation, Navier-Stokes equations and compressible Stokes equations on polygonal domains and, based on the corner singularity expansion, introduce recently developed numerical results for the finite element methods.
? The boundary value problem of the Poisson equation on polygonal domains: Basic regularity result and the finite element method, based on the corner singularity expansion.
? The boundary value problem of the Navier-Stokes equations on polygonal domains: Basic regularity result and the finite element method, based on the corner singularity expansion.
? The boundary value problem of the compressible Stokes equations on polygonal domains: Basic regularity result and the finite element method, based on the corner singularity expansion.
