Matrix-free Monolithic Multigrid Methods for Stokes and Generalized Stokes Problems
Daniel Jodlbauer, Ulrich Langer, Thomas Wick +1
We consider the widely used continuous - quadrilateral or hexahedral Taylor-Hood elements for the finite element discretization of the Stokes an…

Robust Preconditioners for Multiple Saddle Point Problems and Applications to Optimal Control Problems
Alexander Beigl, Jarle Sogn, Walter Zulehner
In this paper we consider multiple saddle point problems with block tridiagonal Hessian in a Hilbert space setting. Well-posedness and the related issue of preconditioning are disc…

Preconditioning Inverse Problems for Hyperbolic Equations with Applications to Photoacoustic Tomography
Alexander Beigl, Otmar Scherzer, Jarle Sogn +1
This paper is concerned with robust preconditioning of wave equations constrained linear inverse problems from boundary observation data. The main result of this paper is a concept…
