In this work, we propose a local Fourier analysis for multigrid methods with coarsening by a
factor of three for the staggered finite-difference method applied to the Stokes equations. In …

In this paper we study and compare two multigrid relaxation schemes with coarsening by
two, three, and four for solving elliptic sparse optimal control problems with control …

In this work, we propose three Braess-Sarazin-type multigrid relaxation schemes for solving
linear elasticity problems, where the marker and cell scheme, a finite difference method, is …

Large linear systems of saddle-point type have arisen in a wide variety of applications
throughout computational science and engineering. The discretizations of distributed control …

We consider a block‐structured multigrid method based on Braess–Sarazin relaxation for
solving the Stokes–Darcy Brinkman equations discretized by the marker and cell scheme. In …
