Hybridizable Staggered Discontinuous Galerkin Methods for Polyharmonic Equations on Polytopes

Long Chen, Xuehai Huang, Yule Sun +1

Hybridizable staggered discontinuous Galerkin methods are developed for arbitrary-order polyharmonic equations $(-\hat{I}”{)}^{m}u=f$ on shape-regular polytopal meshes in ${\mathbb{R}}^d$, for…
