The high-order finite element Duffy de Rham complex and low-order-refined preconditioning
Will Pazner
In this work, we construct high-order finite element spaces for the de Rham complex on triangular meshes amenable to low-order-refined preconditioning. The spaces are constru…

Subspace and auxiliary space preconditioners for high-order interior penalty discretizations in
Will Pazner
In this paper, we construct and analyze preconditioners for the interior penalty discontinuous Galerkin discretization posed in the space . These discretizations a…
