Structure-Preserving Discretization and Model Reduction for Energy-Based Models

Robert Altmann, Attila Karsai, Philipp Schulze

We investigate discretization strategies for a recently introduced class of energy-based models. The model class encompasses classical port-Hamiltonian systems, generalized gradien…

Time discretization schemes for hyperbolic systems on networks by $ε$ -expansion

Robert Altmann, Christoph Zimmer

We consider partial differential equations on networks with a small parameter $ε$ , which are hyperbolic for $ε > 0$ and parabolic for $ε = 0$ . With a combination of an $ε$ -expansion an…
