Convergence analysis of a covolume scheme for Maxwell's equations in three dimensions
This paper contains error estimates for covolume discretizations of Maxwell’s equations in three space dimensions. Several estimates are proved. First, an estimate for a semi-dis...

Application of Hierarchical Decomposition: Preconditioners and Error Estimates for Conforming and Nonconforming FEM
A successive refinement of a finite element grid provides a sequence of nested grids and hierarchy of nested finite element spaces as well as a natural hierarchical decompositio...
