Robust Parameter-Free Multilevel Methods for Neumann Boundary Control Problemsa on the boundary of a convex polygonal domain. The optimal control unknown is the one for which the harmonic extension approximates best a specified target in the interior of the domain. We propose a multilevel preconditioner for the reduced Hessian resulting from the application of the Schur compl

A Subspace Correction Method for Nearly Singular Linear Elasticity Problemsuations arising from a nonconforming finite element discretization based on reduced integration.We introduce a specific space decomposition into two overlapping subspaces that serves as a basis for devising a uniformly convergent subspace correction algorithm. We consider the equations of linear ela

https://doi.org/10.1007/978-3-031-67165-4In this work, we study mesh regularization in Bank-Holst parallel adaptive paradigm when adaptive enrichment in both . (geometry) and . (degree) is used. The paradigm was first introduced by Bank and Holst in and later extended to .-adaptivity in . In short, the paradigm can be summarized in the following steps.

Lecture Notes in Computer ScienceWe present an Algebraic Multigrid (AMG) method for graph Laplacian problems. The coarse graphs are constructed recursively by pair-wise aggregation, or matching as in and we use an Algebraic Multilevel Iterations (AMLI) for the solution phase.
