Heat Conduction with Phase Change in Permafrost Modules of Vegetation Models
David Hötten, Jenny Niebsch, Ronny Ramlau +1
We consider the problem of heat conduction with phase change, that is essential for permafrost modeling in Land Surface Models and Dynamic Global Vegetation Models. These models re…

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…
