review text: The author is concerned with the robustness of multigrid solvers for discrete rotated anisotropic diffusion equations and discrete convection-diffusion equations with respect to variations in problem-related parameters. In particular, he develops two-grid methods relying on Schur complement approximations whose convergence is studied by means of a Fourier analysis. Numerical results involving the multigrid \(W\)-cycle display robustness at convergence rates between 0.3 and 0.6.
