题目：hp-version discontinuous Galerkin  methods and Hybrid high order methods on polygonal and polyhedral meshes

摘要：In this series of lectures, we will review the recent development of the hp-version discontinuous Galerkin (dG) methods and Hybrid High-order (HHO) methods on polygonal/polyhedral elements. These two methods stand for two different but popular numerical methods for solving PDEs based on polytopic grids. We will spent five lectures for discussing about the mathematics of the hp-version dG methods on polytopic meshes, including: the design of the methods, the stability analysis, a priori/posteriori error analysis and the application of the methods. There will be also be one lecture on the introduction of the HHO methods for elliptic problems. Here is the list of the six lectures:

1. hp-version dG method on polygonal meshes I: Basic theory, why dG, polygonal meshes,  polynomial inverse inequality

2. hp-version dG method on polygonal meshes II: hp-approximation theory, a priori error analysis.

3. hp-version dG method on polygonal meshes III: advection-diffusion-reaction problem and fourth order PDEs

4. hp-version dG method on polygonal meshes IV: space-time dG methods for solving time dependent PDEs and GPU computation.

5. hp-version dG method on polygonal meshes V: A posterior error analysis dG on polygonal meshes for second order PDEs and Fourth order PDEs.

6. HHO methods for solving elliptic PDEs.
