On the analysis of block smoothers for saddle point problems
Lorenz John, Ulrich Rüde, Barbara Wohlmuth +1
In this article, we discuss several classes of Uzawa smoothers for the application in multigrid methods in the context of saddle point problems. Beside commonly used variants, such…
Towards differential geometric characterization of slow invariant manifolds in extended state space: Sectional Curvature and Flow Invariance
Pascal Heiter, Dirk Lebiedz
Some model reduction techniques for multiple time-scale dynamical systems make use of the identification of low dimensional slow invariant attracting manifolds (SIAM) in order to r…
Model reduction for calibration of American options
Olena Burkovska, Kathrin Glau, Mirco Mahlstedt +1
American put options are among the most frequently traded single stock options, and their calibration is computationally challenging since no closed-form expression is available. D…
Positivity for convective semi-discretizations
Imre Fekete, David I. Ketcheson, Lajos Lóczi
We propose a technique for investigating stability properties like positivity and forward invariance of an interval for method-of-lines discretizations, and apply the technique to…
