Workshop Matrix Equations location:Chemnitz date:17 June 2007
In this talk we will extend the geometric multigrid solver
for Lyapunov and Sylvester equations from the previous talk.
We will focus on how we can obtain a robust multigrid solver where the
convergence is independent for a wide class of PDEs, e.g. anisotropic
diffusion. We see how we can apply robust smoothers in a low rank setting
and how we can analyse the convergence with a Local Fourier
